Trivia: Trevor was born Claire Wemlinger. After attending Columbia and the American Academy of Dramatic Arts, she began her acting career in the late '20s in stock. By 1932 she was starring on Broadway; that same year she began appearing in Brooklyn-filmed Vitaphone shorts. She debuted onscreen in feature films in 1933 and soon became typecast as a gang moll, a saloon girl, or some other kind of hard-boiled, but warm-hearted floozy. Primarily in B movies, her performances in major productions showed her to be a skilled screen actress; nominated for Oscars three times, she won the Best Supporting Actress Oscar for her work in Key Largo (1948). In the '50s she began to appear often on TV; in 1956 she won an Emmy for her performance in Dodsworth opposite Fredric March.

Trivia: Relatively few people remember the name Biff Elliot today, but as an actor, he carved a special place for himself in popular culture during the '50s -- in a role that he spent years living down. Born Leon Shalek in Lynn, MA, a working-class town, he aspired to an acting career and came to New York in pursuit of that goal. He got some stage and television work, mostly playing tough, working-class characters, and then a seemingly big break in Hollywood playing the lead role in the crime thriller I, The Jury (1953), directed by Harry Essex. In the history of popular culture, Ralph Meeker might have earned a place playing Mike Hammer in the best movie ever made from one of Mickey Spillane's books; Spillane himself may have played the best Mike Hammer on the big-screen (and Brian Keith the best Mike Hammer on the small-screen); but Biff Elliot had the honor of being the first actor to portray Mike Hammer anywhere in that 1953 movie (made in 3-D) based on the first of the Hammer books. It should have been a breakthrough role, but the movie ended up being an albatross around his neck. Over the next few years, there were other offers for more roles in which, in the manner of Spillane's hero, he was mostly pummeling other characters. Elliot did get some film work in movies such as Between Heaven and Hell, Good Morning, Miss Dove, and The Enemy Below (as the ship's quartermaster) at Fox, and Pork Chop Hill for Lewis Milestone at United Artists, but mostly he worked in television. In 1959, Elliot got a seemingly good break when playwright Clifford Odets happened to see I, The Jury and offered him a role in The Story on Page One, which Odets wrote and directed. Alas, the latter movie fizzled -- mostly thanks to Odets's convoluted approach to directing -- and did nothing to help the career of anyone in it. Elliot was mostly seen on television over the next decade or so in roles of varying sizes -- in the Star Trek episode "The Devil in the Dark" as Schmitter, the mining colony crewman joking about the anticipated arrival of the Starship Enterprise who is dissolved by the title creature in the pre-credit sequence. During the '70s and '80s, he was once again seen regularly in movies, including the Jack Lemmon vehicles Save the Tiger (1973), The Front Page (1975) and That's Life (1986). Elliot died of natural causes at age 89 in 2012.

Trivia: Lead actress, onscreen from the '50s.

Trivia: Character actor Howard McNear made a name for himself on network radio in a vast array of characterizations, from snivelling murderers to dapper French detectives. McNear's best-known radio role was as Doc on Gunsmoke, which ran from 1955 to 1962; his spin on the character was slightly more ghoulish than the interpretation offered by Milburn Stone on television. In films from 1954, the bespectacled, mustachioed McNear was usually cast as a querulous fussbudget. He was spotlighted as Dr. Dompierre in Otto Preminger's Anatomy of a Murder (1959), and was prominently featured in three Billy Wilder comedies, Irma La Douce (1963), Kiss Me Stupid (1964) and The Fortune Cookie (1966). He appeared with frequency on TV in the 1950s and 1960s, often as a foil to such comedians as Jack Benny and Burns and Allen. Howard McNear's most beloved TV characterization was as Mayberry barber Floyd Lawson on The Andy Griffith Show; when McNear suffered a debilitating stroke in 1967, Griffith kept him on the payroll, re-writing the scripts to allow "Floyd" to be seated and non-ambulatory without drawing undue attention to McNear's affliction.

Trivia: Supporting actor, onscreen from 1962.
