Trivia: Australian actor Jesse Spencer launched his career with a long stint (from the mid- to late '90s) on the popular Aussie soap opera Neighbours, playing Billy Kennedy. He followed that up with a number of key supporting roles in acclaimed features, such as that of Marwood de Whichehalse in Mike Barker's R.D. Blackmore adaptation Lorna Doone (2001) before signing on for the lead in Russell Mulcahy's inspirational drama Swimming Upstream (2002). That picture -- about a young man destined to become a champion swimmer despite the setbacks thrown into his path by an abusive father (Geoffrey Rush) became a small-scale hit and earned favorable reviews. After a turn in the Brittany Murphy vehicle Uptown Girls (2003), Spencer landed one of his greatest achievements when he signed on to play Dr. Robert Chase on the Fox medical drama House, and the series quickly became a hit. Offscreen, Spencer made headlines for his romantic involvement with House co-star Jennifer Morrison (Dr. Allison Cameron). The two -- who reportedly met on the set of House -- became engaged during the 2006 holidays.

Trivia: Was a star volleyball player in high school and was named Section Two Volleyball Player of the Year in Pennsylvania. Studied business management in college. Big break came when he was cast as a regular on Fashion House in 2006. Appeared in Lady Gaga's 2011 music video "You and I." Played the recurring role of werewolf Mason Lockwood on The Vampire Diaries. Participated in the Chicago Polar Bear Plunge, which raises money for the Special Olympics, in 2015.

Trivia: Born in London to Grenadian parentage, distinguished actor Eamonn Walker acquired a deep-seated interest in drama at the age of 9, when he witnessed Sidney Poitier acting; the experience helped the young man perceive drama as a powerful tool to change individual lives. Walker began his professional life in repertory theater by touring across United Kingdom and tackling roles in smaller regional productions, then formally honed his craft in South London's Albany Empire. Thereafter, Walker unveiled an ability to seamlessly segue between portrayals of African Americans, West Indians, and Africans. He first bowed in front of the camera in the early '90s, but came into his own around the tail end of that decade as the deeply conflicted Muslim/black nationalist Kareem Said on all six seasons of HBO's harrowing prison drama Oz (1997-2003). That marked a watershed assignment that opened up the floodgates to many others, including a small contribution to M. Night Shyamalan's sci-fi thriller Unbreakable (2000), a turn as Baptiste Senior in director Andrew Niccol's political thriller Lord of War (2005), and an uncanny portrayal of blues legend Howlin' Wolf in the period ensembler Cadillac Records (2008). In 2006, Walker drew from his theatrical roots -- and made more than a few headlines -- with a Broadway performance opposite Denzel Washington in Julius Caesar.

Trivia: Best known as Steve, the boyishly charming nice-guy bartender (and the perfect complement to his onscreen romantic partner, snappish Miranda Hobbes) in HBO's blockbuster original series Sex and the City, the slightly diminutive, raven-haired American character actor David Eigenberg was born in Manhasset, NY, on May 17, 1964. As the only boy in a family of six children, Eigenberg moved with his parents and sisters at age four to Naperville, IL, a farming community just outside of the Windy City -- where he remained through the end of adolescence. Eigenberg reportedly struggled as a student, barely scraping by; a handful of run-ins with the law and minor recreational drug abuse allegedly ensued. Eigenberg did graduate from Naperville High School in 1982, however, and was promptly accepted to the University of Iowa, where he planned to study social work. For better or worse, this was not to be, for the Chicagoan ripped his dormitory apart during the first semester and was promptly booted out of the university after five weeks.A stint in the Marines and various construction jobs followed, instilling in Eigenberg healthy amounts of much-needed self-discipline and a sharply honed work ethic. These skills paved the way for Eigenberg's true calling: acting. A love of the dramatic arts had already taken root for the thespian when -- at age 12 -- he had signed on to play a key role in a local production of Kurt Vonnegut's Happy Birthday, Wanda June, and received an outstanding review from a local critic. These fond memories doubtless came flooding back when an adult Eigenberg auditioned -- and was selected for -- a large part in the Dennis Rosa-directed Chicago stage musical One Shining Moment, opposite Megan Mullally and Alan Ruck. Dissatisfied with a mere taste of the theatrical arts and eager to extend acting into a full-time passion, Eigenberg subsequently moved to New York and attended the American Academy of Dramatic Arts, working odd jobs on the side (construction et al.) to put himself through school.Scattered roles followed, including a guest appearance on The Cosby Show and a bit part in the awful 1989 generation-gap comedy Rude Awakening (co-starring Cheech Marin and Eric Roberts), but Sex and the City (which Eigenberg auditioned for out of innumerable hopefuls) represented the actor's first huge break. He reportedly auditioned for a small part, and though the show's producers did not deem him right for the characterization, they felt so impressed by Eigenberg's presence that they created the character of Steve Brady especially for him, as an extension of his own personality; the plan, again, was to create a sincere, committed, down-to-earth male paramour to offset Miranda's (Cynthia Nixon) cynicism.Though initially intended as a temporary part, the popularity of the character among viewers (and Eigenberg's onscreen chemistry with Nixon) led to Eigenberg's permanent inclusion on the show, as well as subsuquent movies.Circa 2002, Eigenberg expanded into film roles by playing the business partner of Richard Gere in Mark Pellington's underrated supernatural thriller The Mothman Prophecies. When Eigenberg's Sex and the City run ended with the wrap-up of that series (at the end of the 2003-2004 season), he continued his cinematic work, first voicing Nermal the Cat in the FX-extravaganza Garfield: The Movie, then playing Reggie, the lover of Alicia Goranson's Myra, in Adrienne Weiss' quirky indie romantic comedy Love, Ludlow. Eigenberg returned to the same genre amid a cast of unknowns with the 2007 film The Trouble with Romance, directed by Gene Rhee. He reprised his role in the Sex and the City movie in 2008 and the sequel in 2010. In 2012, he joined the cast of NBC's Chicago Fire, playing a firefighter in the Windy City.

Trivia: Raven-haired Lauren German made her film debut with a small appearance in the 2000 comedy Down to You. She paid her dues over the following years with minor roles in A Walk to Remember, The Texas Chainsaw Massacre and Hostel: Part II. A much more prominent part came in 2011, when German was cast in the role of Lori Weston on the TV remake of Hawaii Five-0.

Trivia: Actress Monica Raymund learned as much as she could about her craft before getting a serious start on her professional career, graduating from the Juilliard School in New York and participating in Ann Reinking's Broadway Theatre Project for three years. When she decided to pursue an on-screen career, Raymund had little trouble getting started, snagging the role of tough-talking Ria Torres on the crime drama Lie to Me. When Lie to Me ended its three-season run in 2011, Raymund made the seamless transition to the CBS drama The Good Wife, in which she played the character of Dana Lodge.

Trivia: A slightly tough and weathered character actor who specialized in playing gruff, domineering types (including guards, Mafiosos, and authoritarian fathers), Christian Stolte debuted onscreen in the early '90s and went on to distinguish himself with bit parts in films including Novocaine (2001), Road to Perdition (2002), and Stranger Than Fiction (2006). On the small screen, Stolte took on the recurring role of C.O. Keith Stolte during the first two seasons (2005-2007) of the cult series Prison Break. Back on the big screen, he received unusually prominent billing with his wry comic turn as a Mafia hitman assigned to rub out his cousin, in the character comedy Osso Bucco (2007).

Trivia: Is half-Georgian, half-Armenian; moved to the United States at age 2. Appeared in The History Boys at the Timeline Theatre in Chicago in 2009, while he was still attending college. Prepped for his role in Chicago Fire by doing ride-alongs with the Chicago Fire Department. Shared an apartment with Chicago Fire castmates Charlie Barnett and Joe Minoso during the show's first season.

Trivia: Is the youngest of seven siblings. Was accepted to the University of North Texas, but postponed her admittance due to being cast in Friday Night Lights. Is the singer for her band You, Me and the Mountain.

Trivia: Was named the associate artistic director for Teatro Vista in Chicago in 2009. Appeared in the Goodman Theatre's production of A Christmas Carol in the 2011-12 season. Had a memorable recurring role on the Starz series Boss where his character's ears were cut off. Shared an apartment with his Chicago Fire castmates Yuri Sardarov and Charlie Barnett when the show was first picked up.

Trivia: Actor Brian J. White eked out an unusual path to showbusiness. A Massachusetts native and the son of Boston Celtics player JoJo White, Brian attended the Ivy League Dartmouth College, majoring in poly sci, theater arts, and psychology, but his athletic prowess yielded two offers to go professional: one with the NFL and another with the National Lacrosse League. White opted for the NFL, and signed with the New England Patriots, but a sporting injury derailed his career and found him forking off into professional modeling, and then acting. Within the latter arena, White began to specialize in onscreen portrayals of intelligent, polished, and urbane men. The actor took his earliest screen bow with a lead role: that of Tracy Wainwright, a young executive who strikes up an ill-advised affair with his boss, only to find his career jeopardized when he falls in love with another woman, in the 2001 workplace drama Me & Mrs. Jones. Unfortunately for White and his co-stars, that film failed to achieve wide theatrical release in the United States (despite touring the festival circuit), but the actor achieved greater recognition with a multi-episode role on the small-screen police drama The Shield (as Detective Tavon Garris) and supporting turns in the features Mr. 3000 (2004), The Family Stone (2005), and Stomp the Yard (2007). He returned to the small screen in fall 2007, playing Lieutenant Carl Davis in a recurring role on the vampire detective series Moonlight.

Trivia: There's a good reason why actor Steven R. McQueen shares a name with the legendary action star of Bullet and The Great Escape, Steve McQueen. He happens to be the King of Cool's grandson, and his own forays into movies have been unique. He first caught audience's attention with a recurring role on the series Everwood, playing young Kyle Hunter. He later made appearances on shows like Numb3rs and Without a Trace and was eventually cast in the series The Vampire Diaries in 2009. The next year has was cast in Piranah.

Trivia: Wanted to be an actress after seeing The Philadelphia Story (1940) as a young girl. Holds a first-degree blue belt in Brazilian Jiu-Jitsu. Starred in Hulu's first original scripted show, Battleground, as KJ Jameson. Member of the Chalk Repertory Theatre in Los Angeles.

Trivia: Though indie-savvy moviegoers may recognize Eric Mabius for his roles in the mid-'90s art-house hits Welcome to the Dollhouse (1995) and I Shot Andy Warhol (1996), Mabius's journey to mainstream recognition has been slow and steady as the talented actor assuredly made his way to starring in such wide-release films as Resident Evil (2002) and Resident Evil: Apocalypse (2004). Born April 21, 1971, in Pennsylvania, Mabius studied film, dance, and sculpture at Sarah Lawrence College starting in 1990. Gaining experience in numerous off-Broadway roles, the aspiring actor (who often resembled a young Harrison Ford, with that actor's concomitant appeal) soon landed his first film role in director Todd Solondz's satirical Dollhouse. As the object of awkward seventh-grader Dawn "Weinerdog" Weiner's affection, Mabius's humorous performance raised a few eyebrows as well as a few chuckles. Following strongly with roles in Warhol, Lawn Dogs (1997), and The Minus Man (1999), Mabius turned up in increasingly prominent roles, with his turn as a closeted athlete in Cruel Intentions (also 1999) kicking his career into high gear. Taking over for the late Brandon Lee in the role of the Crow for 2000's The Crow: Salvation, Mabius had ironically auditioned for the role of Funboy in the first entry (a role that eventually went to Michael Massee, the actor who fired the gun shot resulting in Lee's untimely death).2002 found Mabius in his most prominent mainstream role to date as he joined the cast of the popular video game turned movie franchise Resident Evil. The film grossed upwards of $100 million giving Mabius enough exposure to land him the only leading male role in the 2004 debut season of Showtime's lesbian drama series The L Word. Though the role was diminished to an occasional guest-spot in subsequent seasons, Mabius remained a presence on the small screen with a multi-episode arc as Dean Jack Hess on Fox's The O.C. and a starring role in the short-lived ABC mystery show Eyes. In 2005, Mabius appeared in two minor films: the police actioner Venice Underground and the slasher movie Reeker. In the former, the actor plays an undercover agent who must help his partners track down the murderer of a narcotic agent, in the latter, the obnoxious Ecstasy supplier of a serial killer's victim. He also made a particularly huge splash on the small screen, as Daniel Meade, the fashion editor boss of "ugly duckling" Betty Suarez (America Ferrera) in the blockbuster prime-time series Ugly Betty (2006), adapted from a popular Spanish telenovela.

Trivia: A blonde beauty who began her career as a ballerina, Izabella Miko moved between Poland and America before establishing herself in the Hollywood scene with roles in such popular features as Coyote Ugly (2000) and The Forsaken (2001).Born in Lodz, Poland, in 1981, Miko studied ballet, voice, and piano at Poland's Chopin Music School before a choreographer recruited her at the age of 14 to move abroad and join the School of American Ballet. Relocating to New York, Miko studied at the New York City Ballet and the Lee Strasberg Institute before a back injury brought her dancing career to a halt. Moving back to Poland and appearing in numerous films in the following few years, Miko moved back to the United States in the mid-'90s and, with her acting experiences intact, began to make a bid for the big time on the silver screens of Hollywood. She had a small recurring role on the HBO western series Deadwood, and went on to appear in Save the Last Dance 2, Dark Streets, The Spiderwick Chronicles, and 2010's big-budget spectacle Clash of the Titans.
