Those who heard the voice of actor Tony Roberts on the 1970s dramatic series "The CBS Radio Mystery Theater" may not have been aware that by performing before a mike, he was maintaining a family tradition. Roberts was the son of announcer Ken Roberts and the cousin of actor Everett Sloane, both alumni of such golden age radio endeavors as "The Mercury Theatre of the Air" and "The Shadow." After studying acting at Northwestern University, the lanky, curly headed Roberts struck out for New York, working in commercials ("Boss, you've got bad breath! Bad breath!") before landing a regular stint on the TV soap opera The Edge of Night. His long-term friendship and professional relationship with comedian/writer/director Woody Allen began when Roberts was cast as Diane Keaton's husband in Allen's Broadway production Play It Again, Sam in 1969. Since that time, Roberts has appeared in such Allen efforts as Annie Hall (1977), Stardust Memories (1980), A Midsummer Night's Sex Comedy (1982), and Radio Days (1987). On prime time TV, Roberts co-starred in the 1977 adventure series Rossetti and Ryan. In 1995, Tony Roberts co-starred on Broadway with Julie Andrews, playing a flamboyant homosexual cabaret entertainer in the musical version of Andrews' 1981 movie vehicle Victor/Victoria.
