Other than the four Gildersleeve films, Peary appeared in the Walt Disney movie A Tiger Walks (1964) and the Elvis Presley film Clambake (1967).
In the 1970s Peary found work as a voice actor, most memorably as Big Ben, the whale with a clock in its tail, in two Rudolph the Red-Nosed Reindeer productions, Rudolph's Shiny New Year (1976) and Rudolph and Frosty's Christmas in July (1979), the latter being Peary's final acting credit.
