The Office Boy (1930)

A romance between two office workers--knockoffs of Mickey and Minnie Mouse--is threatened by their lecherous boss. This blatant rip-off of Disney's Mickey Mouse is indeed a fascinating effort. Not only is it most agreeably quaint, but it's remarkably fast-paced. And even better still, it's visually well-stocked with a host of neat gags. The superbly integrated music score rates as an outstandingly entertaining bonus.
