Versatile American character actor Wayne Knight has been frequently on stage, screen and television since the late 1970s. In the early '80s, he temporarily left acting (after appearing over 1,000 times in the play Gemini) to become a private detective. In 1986, Knight returned to film in The Sex O'Clock News. He has worked with a number of distinguished directors including Oliver Stone, Kenneth Branagh and Steven Spielberg playing roles ranging from comics to villains.
On television, he is best known for playing the oily, self-serving postman Newman on the long-running sitcom Seinfeld, and Officer Don on the outworldly comedy Third Rock From the Sun. ~ Sandra Brennan, All Movie Guide.
