From his first appearances in the mid-'70s onward, Eddie Deezen has enlivened many a film and TV show, playing a multitude of nerdish, anal-retentive pop-culture freaks. In I Wanna Hold Your Hand (1978), his idolatry of the Beatles extended to his adopting the personality and mannerisms of Ringo Starr; and in WarGames (1983), he's the ultimate technogeek, spouting out computer-ese with such gleeful abandon that you'd think people were really interested in what he had to say. 

In later years, he has devoted much of his time to cartoon voice-overs and the cheapjack output of indie producer Fred Olen Ray. On television, Eddie Deezen played zany maintenance man Eddie Malvin during the 1984-1985 season of Punky Brewster.
