Factual error: Despite the film building to a climax during a total solar eclipse, which requires a New Moon, the film constantly shows a Full Moon, which never changes phase over the weeks the film takes place.
Factual error: The Dragonball gang falls into Yamcha's trap. The bike nosedives into the hole, with Bulma driving (Muten and Goku should by every mean have been able then to jump to safety, but let's forget about that a moment). Goku and Muten somehow land first, and Bulma comes down last after a couple seconds, screaming. Not really making sense from a physical standpoint. (00:38:05)
Factual error: Piccolo evaporates a lake to more comfortably search for a dragonball at the bottom. When he retrieves the ball, he's surrounded by various green-yellowish bushes, which certainly would have not grown at the bottom of a lake. (00:34:30)
