Il trio infernale

During the scene where Echo and company are fleeing the pet store, Echo decides to take his pet ape with them. The "ape" was actually a three-foot-tall chimp who was made to appear gigantic with camera trickery, a specially built smaller-scale set to make it look bigger, and perspective shots. When Echo removes the ape from his cage, the shot shows Echo (with his back turned to the camera) unlocking the cage and walking the ape to the truck. The ape appears to be roughly the same size as Echo. This effect was achieved by having dwarf actor Harry Earles (who played "Tweedledee" in the film) play Echo for these brief shots, and then cutting to the normal-sized Lon Chaney, making it seem as though the ape is gigantic.

The Ape at the pet store is clearly a chimpanzee, but it is depicted as larger than a real chimpanzee can grow.

Turner Classic Movies showed an 86-minute version with a music and sound effects that was recorded in the 1970s by MGM from a stock music library for syndication. The tints for this edition are incorrect.
