Patrick Loubert was one of the founders of the Canadian animation studio, Nelvana Limited, along with Clive A. Smith and Michael Hirsh. He has produced, and executive-produced, much of the company's most memorable fare.

At the beginning of his career, Loubert published The Great Canadian Comic Books, a 1971 book focusing on the early days of local comic lore, with partner Hirsh. Under the alias of Speed Savage, the name of an obscure comic book hero, he wrote the 1972 live-action cult film, Voulez-vous coucher avec God?. With Don Haig, he scripted and directed 125 Rooms of Comfort, another live-action project, in 1974.
