Other mistake: As they're chasing the giant fish and the ship is bouncing on the waves, we can see in some shots a major design flaw - the ship has no rudder.
Sinbad: Legend of the Seven Seas (2003)
1 other mistake
Directed by: Tim Johnson, Patrick Gilmore
Starring: Brad Pitt, Michelle Pfeiffer, Catherine Zeta-Jones, Joseph Fiennes
Continuity mistake: When Sinbad and his men attack Proteus' ship and Proteus is fighting, the neck of his shirt gets torn. In each shot after this the neck line keeps switching between being torn and not being torn.
Trivia: This was the last hand-drawn animated film that came from the DreamWorks Studio, probably due largely to the fact that it flopped in theatres.
