Continuity mistake: In a bus scene Crash is shown holding a guitar talking about being in the majors. In one scene he's just holding the guitar, the next he has a pair of sunglasses in his hand while holding the guitar. The next scene the sunglasses are gone.

Continuity mistake: Near the end of the movie the camera pans to different villagers as they notice Willow returning after his journey. One of the villagers they show is Willow's wife, although they show her in another scene (a minute or so later) walking from a different area and noticing Willow for the first time (again).
Suggested correction: The first woman we see at 1:59:40 looks like Kaiya but her hair is long (while Kaiya's hair is a short bob), and she wears a long brown dress while Kaiya (at 2:00:15) wears a midcalf reddish-brown dress with a white apron.

In the next scene showing Jake's face & Christy behind him in bed she now has a pillow under her and is much higher up in bed.
