About the film
Perri is a 1957 American adventure film from Walt Disney Productions, based on Felix Salten's 1938 novel Perri: The Youth of a Squirrel. It was the company's fifth feature entry in their True-Life Adventures series, and the only one to be labeled a True-Life Fantasy. In doing so, the Disney team combined the documentary aspects of earlier efforts with fictional scenarios and characters.
