Continuity mistake: The shot of Mitch's house across the bay that the store manager shows Melanie is a matte drawing and doesn't look anything like the house we eventually see (no tall structure behind it, no long road that Mitch uses to meet Melanie on the other side of the bay, and no low treeless hills behind the barn).

Continuity mistake: When Mitch unwraps the cotton to put peroxide on Melanie's cut, the ashtray on the table is empty. Mitch never lets the piece of cotton out of his fingers until he has Melanie hold it on her head, and no one else touches the cotton on the table, yet near the end of the scene another used piece of cotton appears in the ashtray.
