Senor Droopy (1949)

Continuity mistake: When the announcer tells Droopy and the wolf about the prize they can have if they win the bullfight, there is a red wall behind the announcer that keeps disappearing and re-appearing between shots.

Continuity mistake: When we see the wolf reading a magazine in his room, he is holding the magazine with his left hand, but a close-up shot shows him holding the magazine with both hands.

Continuity mistake: Towards the end of the cartoon, the bull draws a moustache and beard on Lina Romay on Droopy's magazine, but when Droopy shows the magazine to the announcer after winning the bullfight, the moustache and beard are gone.

Trivia: The first MGM cartoon in which Droopy is called by his name on-screen.
