Mumy was later cast in ''[[Bless the Beasts and Children (film)|Bless the Beasts and Children]]'' (1971) as Teft, a leader in a group of misfit teenage boys resolved to save a herd of bison from hunters.

In 1974, Mumy played Nick Butler in the pilot episode of NBC's ''[[The Rockford Files]]'' and made an appearance in a later episode in season 1 as a sidewalk artist.
