Stretch Films Inc. is the production company that sponsors Courage the Cowardly Dog. It was founded in 1991, by John R. Dilworth.

The production logo features a crudely drawn mouth, the mouth laughs and smiles revealing 12 teeth that spell out "Stretch Films" with "Stretch" being on the top row and the "Films" on the bottom row, Inc. is seen below the mouth.  There is also a Logo that was only on 2 episodes of Courage the Cowardly Dog, "Courage the Fly" (Season 2, Episode 6) and "Little Muriel" (Season 1, Episode 13) and are not on reruns of these episodes. It is a Skydiver with a Banana in his ear. He dances in the logo. You can hear the mouth laugh, but the mouth doesn't move.  The Skydiver was played by John R. Dilworth. This Logo is extremely hard to find.
