Abu Hassan is only a head or two taller than Popeye. Abu enters a cave with a door just tall enough to admit himself and his mount, but seconds later Popeye comes up to the same door which now seems to be ten times the height of a man.
During the battle scene with Abu Hassan and the forty thieves,
the dialogue, the sound effects, and partially the music are out of sync with the animation. This was rectified on the DVD release of "Popeye the Sailor: 1933-1938, Volume 1."
