Nelvana

Nelvana is a Canadian animation company which collaborated with Jim Henson Productions on Dog City, producing the animated segments. Founded in 1971 by Michael Hirsh, Patrick Loubert, and Clive A. Smith, the company initially produced a series of short films and television specials, such as The Devil and Daniel Mouse, as well as creating a segment for The Star Wars Holiday Special (1980), introducing bounty hunter Boba Fett.

The studio released its first theatrical animated feature, Rock and Rule, in 1983, which was a financial failure. Nelvana achieved greater successe producing various Care Bears television episodes and feature films, and with many other franchises based on children's books or films, including Babr, Little Bear (based on the Maurice Sendak character), Beetlejuice, and others.
