Trivia: Educated at Yale and the Sorbonne, Sam Waterston, born November 15th, 1940, is far more than the "general purpose actor" he was pegged to be by one well-known film historian. A respected player on the stage, screen, and television, Waterston has cultivated a loyal following with his quietly charismatic, unfailingly solid performances. After beginning his career on the New York stage -- where he has continued to perform throughout his long career -- Waterston made his film debut in The Plastic Dome of Norma Jean in 1966. For a long time, his film career was not nearly as remarkable as his work on the stage and television, although non-New York audiences were made acutely aware of the depth and breadth of Waterston's talents when, in 1973, he starred in the television adaptation The Glass Menagerie (appearing alongside Katherine Hepburn) and -- also on TV -- in Tony Richardson's A Delicate Balance. The following year, the actor further impressed television audiences when he starred as Benedick in the CBS TV adaptation of Joseph Papp's staging of Much Ado About Nothing. Also in 1974, Waterston proved to be the best of the screen's Nick Carraways when he was cast in that expository role in the The Great Gatsby; subsequent films ranged from the midnight-movie favorite Rancho Deluxe (1975) to the unmitigated disaster Heaven's Gate (1981). In the late '70s, Waterston was "adopted" by Woody Allen, joining the director's ever-increasing unofficial stock company for such films as Interiors (1978), Hannah and Her Sisters (1986), September (1987), and Crimes and Misdemeanors. Waterston was nominated for an Academy award for his powerful portrayal of a conscience-stricken American journalist in The Killing Fields (1984); three years later he appeared in Swimming to Cambodia, Spalding Gray's acclaimed documentary about the making of the film. Subsequent film appearances included a turn as Kathleen Turner's hilariously timid husband in Serial Mom (1994) and a role in Ismail Merchant's The Proprietor in 1996.However, Waterston has continued to make his greatest mark on television, starring in the acclaimed The Nightmare Years in 1989 and in the similarly lauded series I'll Fly Away and Law & Order. In addition, he has gained a certain amount of fame playing Abraham Lincoln multiple times: In 1988, he starred in Gore Vidal's Lincoln on television, while he won a Tony nod playing him in the Lincoln Center production of Abe Lincoln in Illinois and supplied the president's voice for Ken Burns' documentary The Civil War.Though Waterson is most recognizable for his work in Law & Order, he took on a variety of other television roles throughout the 1990s and 2000s, among them including a turn as the District Attorney Forrest Bedford in I'll Fly Away (the role would win him an Golden Globe). In 2012, Waterson joined the cast of HBO's The Newsroom.

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: S. Epatha Merkerson is a Tony-nominated and Obie-winning, African-American stage actress, but is best known for her portrayal of detective squad chief Lt. Anita Van Buren in the series Law and Order. Born and raised in Detroit as the youngest of five children, she was a fine arts graduate of Wayne State University and began her New York theater career in the late 1970s. Merkerson was nominated for a Tony award for Best Actress for her performance as Berniece in The Piano Lesson and won an Obie award in 1992 for her work in I'm Not Stupid. Her screen credits include Jacob's Ladder and Loose Cannons and, perhaps most visibly, her role as Joe Morton's terrified wife in James Cameron's Terminator 2: Judgment Day. Merkerson made her television debut as Reba, the Mail Lady on Pee Wee's Playhouse, and has appeared on The Cosby Show, among other series, but her most important single television appearance may have been in the first season Law and Order show "Mushrooms," in which she portrayed the grief-stricken mother of an 11-month-old boy who is shot accidentally. Her work was not only memorable to the audience during that key first season, but also to the producers, who later picked Merkerson for the role of the new detective squad chief in the series' fourth season--a role she continued to play for over ten years. Merkerson's talent on the small screen led to roles in numerous TV movies such as Breaking Through and A Mother's Prayer, as well as roles in such films as Radio and The Rising Place. Still, her monumental gifts in both presence and interpretation may not have truly been utilized until she took the part of a strong matriarch who runs a 1960's boarding house in HBO's mini series Lackawanna Blues. Her first leading role in almost twenty years on screen, her performance earned her an Emmy Award as well as a Golden Globe. After her triumphant turn in Lackawanna Blues she returned to the big-screen in Craig Brewer's follow-up to Hustle & Flow, Black Snake Moan co-starring Christina Ricci and Samuel L. Jackson.Over the coming years, Merkerson would appear in a number of films, like The Six Wives of Henry Lefay and Mother and Child.

Trivia: Fred Dalton Thompson spent 25 years as an active Nashville and Washington, D.C., attorney before making his film debut playing himself in a 1985 retelling of the true tale of a Tennessee woman who took on the state's crooked governor in Marie. When Thompson won more acclaim than the film's stars Sissy Spacek and Jeff Daniels, he decided to add "character actor" to his resumé, and went on to appear in numerous major features. Standing 6'5," he was a commanding presence and was usually cast as an authoritarian. Thompson put his film career on hold when he made a successful bid to become a Tennessee senator in 1994, then picked up where he left off when his term ended, playing DA Arthur Branch on Law & Order, along with other supporting film roles. Thompson returned to politics with an attempt at the 2008 presidential election, but was unsuccessful, and soon resumed his acting career. He played horse breeder Arthur Hancock in Secretariat (2010) and appeared in the Hank Williams biopic The Last Ride (2011). One of his final acting roles was as an FBI Director in the short-lived NBC series Allegiance in 2015. Thompson died later that year, at age 73.
