Robert Nadder played character roles on stage, screen, and television. In the mid-'50s, he appeared in New York theatrical productions such as The Great White Hope. Though he moved to Los Angeles in the early '70s, and started appearing occasionally on television in mid-decade, he primarily earned his living on stage. Nadder made his first film appearance in The Main Event (1979) and Love at First Bite (1979). His subsequent film work was sporadic. ~ Sandra Brennan, All Movie Guide
