Trivia: American actress Danielle Panabaker launched her career as a teenage ingenue in the late '90s, first with bit parts in such series as The Bernie Mac Show, CSI: Crime Scene Investigation, and The Division, then with a string of well-received feature roles on the big and small screens. These included parts in Stuck in the Suburbs (2004), Yours, Mine & Ours (2005), and Mr. Brooks (2007). In the latter, a psychological thriller helmed by Bruce A. Evans, Panabaker plays Jane Brooks, the daughter of a seemingly normal man (Kevin Costner) who just happens to be a serial murderer -- the notorious "Thumbprint Killer."By all accounts a child prodigy, Panabaker graduated from high school about four years early (at age 14!) as valedictorian of her class; she then attended UCLA. In addition to the aforementioned roles, Panabaker was among the cast of the Fred Schepisi-directed HBO miniseries Empire Falls (2005), adapted from the acclaimed novel by Richard Russo and starring Paul Newman, Ed Harris, Aidan Quinn, and Helen Hunt. She also portrayed James Woods's daughter on the prime-time series Shark (2006), a drama about a ruthless celebrity attorney (Woods). Up on the big screen, Panabaker earned genre cred with roles in Friday the 13th, The Crazies, John Carpenter's The Ward, and Piranha 3DD, though it was small screen work on shows like Medium, Law and Order: LA, Necessarry Roughness and Grimm that served as the bread and butter of her career. In 2014, she originated the role of Dr. Caitlin Snow on the CW series Arrow, which led to her regular role playing the character on The Flash.

Trivia: Jesse L. Martin is proof that talent and popularity are not mutually exclusive. When the award-winning stage actor joined the cast of NBC's Law and Order in its tenth season, the program's already high ratings increased by 40 percent. Martin's debut episode drew the largest audience in Law and Order's history and positive press attracted more viewers throughout the season. The once starving artist is now both a critic's darling and one of T.V. Guide's "Sexiest People on Television," confirming that he is an actor with genuinely wide appeal. Martin was born Jesse Lamont Watkins on January 18, 1969, in Rocky Mountain, VA. He is the youngest of five sons. Martin's parents, truck driver Jesse Reed Watkins and college counselor Virginia Price, divorced when he was a child. Ms. Price eventually remarried and the boys adopted their stepfather's surname. When Martin was in grade school, the family relocated to Buffalo, NY, and the move was not an immediate success: Martin hated to speak because of his thick Southern accent and was often overcome with shyness. A concerned teacher influenced him to join an after-school drama program and cast him as the pastor in The Golden Goose. Being from Virginia, the young Martin played the character the only way he knew how: as an inspired Southern Baptist preacher. The act was a hit, and Martin emerged from his shell. The actor attended high school at Buffalo School for the Performing Arts, where he was voted "Most Talented" in his senior class. He later enrolled in New York University's prestigious Tisch School of the Arts Theater Program. After graduation, Martin toured the states with John Houseman's Acting Company. He appeared in Shakespeare's Rock-in-Roles at the Actors Theater of Louisville and The Butcher's Daughter at the Cleveland Playhouse, and returned to Manhattan to perform in local theater, soap operas, and commercials. Finding that auditions, regional theater, and bit parts were no way to support oneself, Martin waited tables at several restaurants around the city. He was literally serving a pizza when his appearance on CBS's Guiding Light aired in the same eatery. Martin made his Broadway debut in Timon of Athens, and then performed in The Government Inspector with Lainie Kazan. While employed at the Moondance Diner, he met the late playwright Jonathan Larson, who also worked on the restaurant's staff. In 1996, Larson's musical Rent took the theater world by storm -- with Martin in the part of gay computer geek Tom Collins. The '90s update of Puccini's La Bohème earned six Drama Desk Awards, five Obie Awards, four Tony Awards, and the Pulitzer Prize. Martin soon landed roles on Fox's short-lived 413 Hope Street and Eric Bross' independent film Restaurant (1998). Ally McBeal's creator, David E. Kelly, attended Rent's Broadway premiere and remembered Martin when the show needed a new boyfriend for Calista Flockhart's Ally. The actor's performance as Dr. Greg Butters on Ally McBeal caught David Duchovny's eye, who then cast Martin as a baseball-playing alien in a 1999 episode of The X-Files that he wrote and directed. While still shooting Ally McBeal, Martin heard rumors that actor Benjamin Bratt planned to leave the cast of Law and Order. Martin tried out for the show years before and won the minor role of a car-radio thief named Earl the Hamster, but decided to wait for a bigger part. With the opportunity presenting itself, Martin begged Law and Order producer Dick Wolf for Bratt's role. Wolf hoped to cast him, and upon hearing that CBS and Fox both offered Martin development deals, he gave the actor the part without an audition. During his first year on Law and Order, Martin co-produced the one-man show Fully Committed, about the amusing experiences of a waiter at an upscale restaurant. A skilled vocalist -- he sang in Rent, on Ally McBeal, and The X-Files -- Martin later appeared in the Rocky Horror Picture Show anniversary special and hopes to star in a big-screen biography of his mother's favorite singer, Marvin Gaye. Over the coming decade, Martin would appear in several more pictures, like The Cake Eaters, the big screen adaptation of Rent, and the TV series The Philanthropist.

Trivia: Perhaps best known to Heroes viewers as genetics professor Mohinder Suresh, who begins to believe that normal people are being instilled with extraordinary powers while continuing his murdered father's work, actor Sendhil Ramamurthy got his breakthrough on the small-screen with a role on the U.K. war drama Ultimate Force, and went on to appear in such stateside shows as Grey's Anatomy and Numb3rs. Despite his success on television, it was on the stage that the Webber Douglas Academy of Dramatic Art graduate got his start, with roles in the Royal Shakespeare Company's West End production of A Servant to Two Masters and the Soho Repertory Theater production of Tom Stoppard's Indian Ink helping to establish Ramamurthy as a formidable stage presence.
