Trivia: Like a lot of girls born into the upper-middle-class suburb of Pasadena, CA, Sophia Bush caught a whiff of the Hollywood air just down the road and took an interest in acting at an early age. After getting her feet wet in school plays at the Westridge School for Girls, she graduated in 2000 and enrolled at the University of Southern California, where she majored in journalism and minored in theater. It was that minor interest that proved to be her greatest passion, however, and in 2002, at the age of 20, she scored her first movie gig with a small role in National Lampoon's Van Wilder.Another onscreen role would follow in 2003, and a much more substantial one. Bush was cast as sassy cheerleader Brooke Davis in the WB series One Tree Hill. She left school to work full-time on the series, which paid off when One Tree Hill proved to be a huge hit. In addition to the professional success that the show brought her, the program also featured Bush's onscreen romance with co-star Chad Michael Murray -- which soon turned into a real-life love affair. The two were wed in 2005, but unfortunately, the union was not to last. After just five months, the two separated and eventually divorced, though they remained co-stars on the series. Bush took the personal hit in stride, continuing to act in additional projects such as Supercross: The Movie and the popular 2006 comedy John Tucker Must Die. Bush also proved to have a knack for tense and scary subject matter, from a recurring part on the series Nip/Tuck to a starring role in the 2006 horror flick Stay Alive. In 2007, she appeared in an even bigger horror movie as the female lead in a remake of The Hitcher, starring opposite veteran actor Sean Bean. While building up her impressive acting resumé, Bush still didn't lose the interest in journalism that she pursued in college, working as an assignment editor for Annenberg TV News when she wasn't on-set.Bush returned to TV in the short-lived sitcom Partners before playing the recurring role of detective Erin Lindsay on Chicago Fire. Her character was part of the planned 2014 spin-off, Chicago P.D.

Trivia: A boyishly handsome boxer-turned-actor who turned in his gloves for real after making his screen debut as a pugilist in the 1992 drama Gladiator, New York-born film and television star Jon Seda rose through the ranks in the '90s to make a name for himself as a bit player in such high-profile films as Carlito's Way and Twelve Monkeys -- though it wasn't until his 1997 debut on television's Homicide: Life on the Streets that audiences truly sat up and took notice. Those who had been following Seda's career since his early days had little doubt that the rising young star had what it took to make it as an actor, and following an Independent Spirit Award-winning role as a flawed but well-meaning husband and father in the 1994 drama I Like It Like That, major offers quickly began pouring in. An impressive run in the mid-'90s found Seda turning up in everything from such high-profile Hollywood fare as Primal Fear to such little-seen efforts as New York Cop and Michael Cimino's The Sunchaser -- the latter of which offered Seda in a particularly memorable role as a terminally-ill juvenile delinquent who kidnaps his doctor in hopes of finding a mythical healing lake. Following an impressive turn in the hit HBO prison series Oz, Seda hit his stride on the small screen with a turn as Detective Paul Falsone on Homicide: Life on the Street. By this time Seda was becoming a familiar face to audiences, and in 2000, he once again laced up his boxing gloves for a role opposite Jimmy Smits in the well-received feature Price of Glory. Despite his prominence and success in film and television, it still seemed as if Seda was awaiting the breakout role that would truly make him a household name. In 2002 he proved that he could carry a film when he took the lead in the street-gang drama King Rikki, with a role on the 2004 UPN series Kevin Hill, marking what fans hoped would be a successful return to the small screen.

Trivia: Connecticut native Jesse Lee Soffer began his career at the tender age of eight when he appeared in the film Matinee, about the sci-fi movies that were popular in the 1950s. At the time, the youngster was performing under the stage name Jesse Lee, and he used that name when he appeared in many films throughout the '90s, such as The Brady Bunch Movie and Safe Passage. By the time he joined the cast of the well-known, long-running daytime soap opera As the World Turns in 2004, however, he was acting under his full name, Jesse Lee Soffer.

Trivia: Stone-jawed and puppy-eyed, Elias Koteas has the enviable ability to call on both his distinctive looks and talent to portray a variety of complex, often troubled characters. Koteas is one of Canada's most prominent and well-respected actors, and during the late '90s, he began to amass international critical attention for his work in a number of high profile films, including David Cronenberg's Crash (1996) and Terrence Malick's The Thin Red Line (1998).Koteas, who is of Greek ancestry, was born in Montreal on March 11, 1961. His father was a mechanic for the Canadian National Railways and his mother worked as a hatmaker; Koteas himself planned to be an architect until his teenage introduction to acting changed his plans. He was particularly inspired by Nick Nolte's performance in the TV miniseries Rich Man, Poor Man; little did Koteas know that two decades later, he would be starring opposite Nolte in The Thin Red Line. After beginning his education at Montreal's Vanier College, Koteas left to study at New York's prestigious American Academy of Dramatic Arts in 1981. Following his graduation, he went to New York's Actors Studio, where he studied under Ellen Burstyn and Peter Masterson. The actor made his film debut in the Mary Steenburgen drama One Magic Christmas in 1985 and went on to do supporting work in a variety of films that included Francis Ford Coppola's Gardens of Stone (1987), Some Kind of Wonderful (1987), Coppola's Tucker: The Man and His Dream (1988), and She's Having a Baby (1988). In 1989, he earned a Genie Award nomination (Canada's equivalent of the Oscar) for his portrayal of the title character of Malarek: A Street Kid Who Made It; two years later, he earned additional acclaim for his performance as a voyeuristic insurance adjustor in Atom Egoyan's The Adjuster. It was for his portrayal of an embittered DJ in another of Egoyan's films, Exotica (1994), that Koteas garnered his second Genie nomination; following this critical success, he began to appear in an increasing number of high profile productions.Koteas was subsequently featured to great effect as the creepy Vaughan in David Cronenberg's controversial Crash (1996), and he invested his brief but pivotal role as Holly Hunter's mystery man in the acclaimed Living out Loud (1998) with memorable charisma. In The Thin Red Line, he managed to stand out from his accomplished co-stars -- who included Nolte, Sean Penn, John Cusack, and Ben Chaplin -- as Captain Storos, an alienated, idealistic soldier who refuses his superior's orders to send his men on a suicidal attack plan. Over the next several years, Koteas would prove to be a consistent force on screen, appearing in films like Shooter, Shutter Island, and Let Me In, as well as the series Combat Hospital.

Trivia: Though she remains best known for her long-running portrayal of Wild West hero Calamity Jane on the HBO period Western Deadwood, classically trained thespian Robin Weigert launched herself to stardom on the theatrical circuit, and had almost ten years of stage work under her belt when she finally moved into filmed roles in Los Angeles. An M.F.A. graduate of NYU's much-revered drama program, Weigert subsequently landed roles in such on- and off-Broadway productions as The Seagull, Noises Off, and Madame Melville. In terms of cinematic and television work, Weigert also gained recognition for her evocation of the Mormon Mother in HBO's Angels in America (which reunited her with Seagull collaborator Mike Nichols) and appeared in the Steven Soderbergh espionage thriller The Good German, opposite George Clooney and Cate Blanchett. Weigert also guest-starred on episodes of Lost, The Unit, Cold Case, and Law & Order: SVU. In 2007, she joined the cast of the cop drama Life as the hardworking Lt. Karen Davis. On the big screen she could be seen in Synecdoche, New York and Things We Lost in the Fire.

Trivia: New Jersey-born actor Brian Geraghty owed his love of acting -- and concomitant celebrity -- to one role that provided him with depthless inspiration: Sean Penn's turn as convicted murderer Matthew Poncelet in Dead Man Walking. After viewing that performance, Geraghty -- unclear after high school about where he wanted to go or what he wanted to do -- made a beeline from his home of Toms River, NJ, to New York City's Neighborhood Playhouse, where he plunged headfirst into classical theater -- and subsequently received a bid to audition for HBO's organized crime drama The Sopranos. Though Geraghty's turn in that blockbuster constituted a small one at best (he played a bumbling counterman who plugs himself in the foot), it caught the attention of Hollywood producers and casting agents, and helped Geraghty immeasurably during a brief period during which he taught surfing in Los Angeles and attended auditions on the side. Feature roles soon followed, in such pictures as Jarhead (2005), We Are Marshall (2006), and Bobby (2006). He ascended to higher billing (but descended several dozen notches in terms of picture quality) as a quarterback smitten with Lindsay Lohan in the critically reviled horror outing I Know Who Killed Me (2007).
