Beginning in the 1950s, the
Canadian-born Mann had small roles in movies, including "The Sting" and "In the Heat of the Night."
On TV, his appearances included "Gunsmoke," ''Bewitched" and Hill Street Blues."
He also did voice work for animated shows, including 1964's "Rudolph."
His son says Mann's last role before retirement was playing a talent agent in the 1991 TV show "Homefront."
