Rist is also known for voicing assorted characters in television shows, games and movies, including Stuffy, the overly-proud stuffed dragon in Doc McStuffins, Whiz in Kidd Video, Star in Balto, Maroda in Final Fantasy X, Choji Akimichi in Naruto, and Michelangelo in the films Teenage Mutant Ninja Turtles (1990), Teenage Mutant Ninja Turtles II: The Secret of the Ooze (1991), Teenage Mutant Ninja Turtles III (1993), and Casey Jones (2011).

He played Ted and Georgette Baxter's adopted son David on The Mary Tyler Moore Show.

However, the idea backfired as most viewers disliked the Oliver character and the plan became moot as ABC had opted to not renew the series even before his debut.

In 1986, Rist had a supporting role as Milo in the action film, Iron Eagle, which was a box-office hit despite being critically panned.
