Trivia: The quiet yet dynamic screen presence of actor Joe Mantegna has made him one of the most powerful supporting actors in Hollywood. Born in Chicago, Mantegna made his acting debut in the 1969 production of Hair. He then joined Chicago's Organic Theatre Company. In 1978, he debuted on Broadway in Working; he also helped write Bleacher Bums, an award-winning play. Still, he did not become well-known until he played a recurring role on the TV show Soap. By 1983 he'd returned to Chicago, where he began working with playwright David Mamet. While playing the lead in Mamet's play Glengarry Glen Ross (1983), Mantegna won a Tony. When Mamet began making films, Mantegna became his actor of choice in works such as House of Games (1987) and Homicide (1991). Prior to that, the actor had played small roles in a number of other films. He also continues to play in a variety of movie genres, working with some of Hollywood's top directors. Mantegna turned producer in 1998 with the crime comedy Jerry and Tom. That trend continued on the small screen as Montenga produced such shows as Midway USA's Gun Stories, Shooting Gallery, and QuickBites, but it was his role as a regular on the CBS series Joan of Arcadia that really kept him in the public eye. Continually returning to his recurring role as Fat Tony on The Simpsons over the next decade, Montegna joined the cast of the hit television series Criminal Minds in 2007, and recieved an Emmy nomination for his performance in the successful mini-series The Starter Wife that same year.

Trivia: Curly haired, sandy-voiced actress Mary Steenburgen is a natural when it comes to playing Southerners, probably because she hails from the region herself. Born in Arkansas on February 8, 1953, Steenburgen was the daughter of a railroad employee. Pursuing drama in college, she headed to New York in 1972, where she worked with an improvisational troupe. She was spotted by Jack Nicholson, who cast her as his feisty "in name only" frontier wife in 1978's Goin' South. Two years later, she won a Best Supporting Actress Oscar for her performance as Melvin Dummar's inamorata in Melvin and Howard (1980).Able to convey a wide age and character range, Steenburgen was effectively cast as a free-spirited Frisco girl in Time After Time (1979), the corseted matriarch of a turn-of-the-century household in Ragtime (1981), prim authoress Marjorie Rawlins in Cross Creek (1983), a long-suffering suburban housewife in Parenthood (1989), and a Marcia Clark-like attorney in Philadelphia (1993). She also portrayed the Jules Verne-loving Western schoolmarm Clara in Back to the Future 3 (1990), a role she perpetuated (via voice-over) on the Back to the Future TV cartoon series. In 1988, she was executive producer of End of the Line, in which she also appeared. Steenburgen's film appearances throughout the 1990s were erratic: some highlights, in addition to Philadelphia, include What's Eating Gilbert Grape (1993), Nixon (1995), and The Grass Harp (1995). In 1999, she starred as Noah's wife in the biblical epic Noah's Ark, sharing the screen with the likes of Jon Voight, F. Murray Abraham, James Coburn, and Carol Kane. As the 21st century began, Steenburgen continued to work steadily in projects such as Life as a House, I Am Sam, Sunshine State, and Elf. She was cast in the CBS drama Joan of Arcadia in 2003. In 2006 she appeared in David Lynch's Inland Empire, and the next year she starred opposite Jodie Foster in the vigilante drama The Brave One. She was cast in the comedies Step Brothers and Four Christmases in 2008, and in 2011 she was the editor who inspires the main character to write the book in The Help.Formerly married for several years to actor Malcolm McDowell, Steenburgen married former Cheers star Ted Danson in 1995. The two have collaborated on a number of projects, including 1994's Pontiac Moon and the made-for-TV Gulliver's Travels in 1996.

Trivia: As the daughter of American child star-turned-cult favorite Russ Tamblyn (Peyton Place, Twin Peaks), Hollywood heartthrob and ingenue Amber Tamblyn inherited the stunning red hair, fair complexion, and acting chops of her famous dad. Born in the early '80s to Russ and wife Bonnie Murray, Tamblyn was discovered by an agent at her school during her preteen years, and soon landed a prominent role as the maniacal tot Emily Quartermaine on General Hospital -- a turn she sustained from 1995 to 2001.Tamblyn guested on such series as Buffy the Vampire Slayer and Boston Public in the early 2000s, and tackled a small role in Gore Verbinski's 2002 shocker The Ring (as one of Samara's unfortunate victims), but the actress failed to generate a sizeable fan base prior to the advent of the fantasy-tinged drama series Joan of Arcadia in 2003. Tamblyn received first billing in that program as Joan Girardi, a seemingly average high school teenager who is tapped by the Almighty to perform various assignments. Joan drew a substantial cult following and outstanding critical assessments (USA Today pegged it as the most promising dramatic series of 2003), but unfortunately, its popularity failed to spread beyond a small enthusiastic band of adherents and it folded within two years.Tamblyn then segued back into film work, with first billing in Ken Kwapis' coming-of-age comedy drama The Sisterhood of the Traveling Pants in 2005, as one of four teenage girlfriends (alongside America Ferrera, Blake Lively, and Alexis Bledel) who make a good-luck pact; the picture received outstanding reviews and ensured continued stardom for Tamblyn. In 2006, the young actress essayed the title role in Hilary Brougher's fine psychological drama Stephanie Daley, about a troubled teenager accused of killing her newborn child. Tamblyn also traveled the programmer route that year with a turn in the horror sequel The Grudge 2. The following year, the actress starred in Beth Schacter's teen comedy Normal Adolescent Behavior and Rigoberto Castaneda's indie thriller Blackout. In the latter -- a high-wire suspense picture about a bunch of people trapped in a hospital elevator -- Tamblyn played a young woman desperate to reach her grandmother before the elderly woman dies. In 2008, she reprised her Traveling Pants role in the sequel, The Sisterhood of the Traveling Pants 2.Amber Tamblyn is also a prolific poet and runs her own website, The Rebel Asylum, with postings of her work. Her volume of poetry Free Stallion was published by Simon & Schuster in 2005.

Trivia: Since actor Jason Ritter hails from a long line of successful entertainers, it seemed only natural that he would eventually try his hand at performing. The son of late Three's Company star John Ritter and the grandson of Hollywood Western star Tex Ritter, young Jason has proven more than capable of carrying on his family's impressive showbiz legacy with roles in such features as Mumford and Freddy vs. Jason. Born in Los Angeles in February of 1980, Ritter made his screen debut opposite father John in the 1990 made-for-television L. Frank Baum biopic The Dreamer of Oz. Though he remained relatively inactive on the screen for much of the 1990s, Ritter continued to train as an actor at both New York University and London's Royal Academy of Dramatic Arts before founding New York City's Irreputable Theater Company. Subsequent roles in the MTV series Undressed and the fantasy-flavored CBS drama Joan of Arcadia quickly elevated Ritter to teen-icon status. A segue into feature territory followed with parts in Freddy vs. Jason (2003) and Swimfan (2002), with his continuing role on Joan of Arcadia serving well to balance his feature and television careers. Unfortunately, personal tragedy struck in 2003 when his father died suddenly of a previously undetected heart condition. Performances in the made-for-television Who's Your Mama? and the Hilary Duff movie Raise Your Voice were quick to follow, and Ritter could also be seen opposite such screen heavies as Steve Coogan, Tom Arnold, and Maggie Gyllenhaal in director Don Roos' ensemble comedy drama Happy Endings. Meanwhile, the rising star continued to rack up impressive credits on both stage and screen, including tackling a sitcom role in the short-lived CBS series The Class (2006-07) and headlining the NBC action thriller The Event in 2010.

Trivia: Sporting a clean-cut, all-American look, Los Angeles-born actor Michael Welch entered the limelight well before his teens and balanced feature and television work with about equal weight. Early small screen projects included guest appearances and recurring roles on series such as Frasier (as a young version of David Hyde Pierce's Niles), Veronica's Closet, and Touched by an Angel, while Welch's feature work invariably emphasized teen-oriented material and often found him cast as a young heartthrob. These big screen endeavors included the teen slasher movie All the Boys Love Mandy Lane (2006), the gore-soaked shocker Day of the Dead (2007), the family-friendly political comedy Choose Connor (2007), and the gothic vampire outing Twilight (2008). Welch also starred as Luke Girardi on the offbeat fantasy series Joan of Arcadia (2003-5).

Trivia: A show business veteran well before his 10th birthday, Secaucus, NJ, native Christopher Marquette covered virtually all the bases of acting at a tender age, making a name for himself in such diverse venues as feature film, Broadway theater, Barney videos, and print advertisements. Marquette and his mother, Tisha, temporarily moved to Los Angeles to accommodate his burgeoning acting career in the fall of 1995 (thus coinciding with TV pilot season), and indeed, he made his biggest splash with guest spots in television programs during the late '90s and early 2000s, including Law & Order, ER, and Touched By an Angel, before scoring a regular role as Marc Delgado (son of doctor Luisa Delgado) on the Lifetime network medical drama Strong Medicine (2001-2006). Meanwhile, Marquette staked out feature territory in such projects as the guilty pleasure slasher opus Freddy Vs. Jason (2003), the crime drama Alpha Dog (2006), and musician-turned-director Fred Durst's gritty drama The Education of Charlie Banks (2007).

Trivia: Involved in amateur theatricals since childhood, Annie Potts received her BFA in theatre arts from Missouri's Stephens College. Potts has been seen in comic supporting roles in films since 1978; she is most closely associated with the part of ditzy secretary Janine Melnitz in the two Ghostbusters flicks of the 1980s. On television, Potts has played Edith Bedelmeyer on the one-season sitcom Goodtime Girls (1980), then enjoyed a longer run as Mary Jo Shively on Designing Women (1986-93). Her characterization of outspoken gourmet chef Dana Paladino on the prime time sitcom Love and War won Annie an Emmy nomination in 1994. Annie Potts has also been featured in a popular series of commercials for a well-known corn-chip product, and has served as national spokesperson for the Women for Arthritis Foundation. In 1996 she was cast as a no-nonsense schoolteacher of troubled inner-city high schoolers in the ABC-TV show Dangerous Minds, a series based on the 1995 Michelle Pfeiffer film of the same name. She voiced the part of Bo Peep in the first two Toy Story films, and in 2003 she took part in a Designing Women reunion. That same year she was the lead in Defending Our Kids: The Julie Posey Story. She appeared intermittently on the Showtime series Huff, and in 2007 she joined the cast of the short-lived series Men In Trees. In 2012 she was cast as one of the leads in the new TV series GCB.

Trivia: Born in Seattle, WA, Constance Zimmer started working steadily on television in her mid-twenties. She made a number of one-off appearances on series as diverse as Seinfeld, Diagnosis Murder, Ellen, and Beverly Hills 90210. After nearly a decade of this type of work, Zimmer landed a recurring roll on the short-lived series The Fighting Fitzgeralds, then landed a large part on the sitcom Good Morning, Miami, a run that lasted for two seasons. Her television career continued with roles on Joan of Arcadia (as Sister Lilly Waters), the showbiz comedy Entourage (as studio exec Dana Gordon), and the short-lived drama In Justice. In 2006, she joined the hit David E. Kelley legal comedy drama Boston Legal for its third season, playing sharp-tongued, assertive lawyer Claire Simms.

Trivia: The older sister of actress and teen pop sensation Hilary Duff, Haylie Duff kicked off her career by focusing more on her skills in front of the camera than her talents behind a microphone. Though she would pen the occasional tune for her younger sibling, it was screen roles in such television hits as Chicago Hope, Boston Public, and, alongside her sister in Lizzie McGuire, that first opened the eyes of the public to the talents of the ambitious rising starlet.Born just two years prior to her sister, Haylie made her screen debut alongside Hilary in the female Western True Women before branching out into features with supporting performances in Dreams in the Attic and I Love Your Work. It was during this period of her career that Haylie would contribute to the soundtracks of such films as A Cinderella Story, Stuck in the Suburbs, and Raising Helen, with a memorable performance in the cult hit Napoleon Dynamite serving well to offer her some indie exposure in addition to her mainstream success. A subsequent return to the small screen found Haylie making a notable impression in That's So Raven, Joan of Arcadia, and 7th Heaven, and in 2006 the it was finally time to join Hilary in the big screen (as sisters no less) for the riches to rags comedy Material Girls. Duff appeared in films such as Love Finds a Home (2009), Love Takes Wing (2009), and A Holiday Engagement (2011). She reprised her role from Napoleon Dynamite in the short-lived cartoon series, and continued to appear in made-for-TV movies like All About Christmas Eve and Christmas Belle.

Trivia: A character actor whose beefy, imposing build (a magazine once listed him as 6'3" and 245 pounds) typecast him as thugs, hoods, and underworld heavies, performer Mike Starr was raised in the Manhattan area, as the son of a meatpacker and a five-and-dime clerk. He attended Long Island's Hofstra University on a drama scholarship, and -- after graduation -- toiled at menial jobs as a bartender and club bouncer before landing his first film role in William Friedkin's gay-themed cop thriller Cruising (1980). Many projects ensued over the following decades, including The Natural (1984), Uncle Buck (1989, in a memorable bit as a drunken clown), Ed Wood (1994), and Jersey Girl (2004). Fans of the gangster-themed comedy Mad Dog and Glory (1993), in particular, might remember Starr -- he played Harold, the wife-beater husband who gets on David Caruso's bad side, and physically suffers for it. In 2007, Starr essayed a rare lead in the character comedy Osso Bucco; he played a gangster unknowingly targeted for death and due for extermination by his cousin.
