John Donald Fiedler was an American actor. His career lasted more than 55 years in stage, film, television, and radio. Fiedler's high, flutey voice was instantly recognizable. He was typecast beginning early in his career for delicate, quiet, nerdy characters, although he also played sneaky villains. His roles included the meek Juror #2 in 12 Angry Men (1957); the benign-seeming gentleman who tries to prevent the Younger family from moving into a whites-only neighbourhood in A Raisin in the Sun (1961); the voice of Piglet in Disney's Winnie the Pooh productions; Vinnie, one of Oscar's poker cronies, in the film The Odd Couple (1968); and Emil Peterson, the hen-pecked milquetoast husband on The Bob Newhart Show.

12 Angry Men is a 1957 American independent legal drama film directed by Sidney Lumet, adapted from a 1954 teleplay of the same name by Reginald Rose. The film tells the story of a jury of 12 men as they deliberate the conviction or acquittal of a teenager charged with murder on the basis of reasonable doubt; disagreement and conflict among them force the jurors to question their morals and values. It stars Henry Fonda, Lee J. Cobb, Ed Begley, E. G. Marshall, and Jack Warden.
