Continuity mistake: During the scene, when Natalie Wood goes with Toots to make-out point after the dance and jumps in the water, it's supposed to be late at night. When they cut back and forth between shots at the waterfalls and Warren Beatty waiting for Natalie on her porch, all the scenes at the falls were shot in broad daylight, while the ones of Warren on the porch are at night.
Continuity mistake: The female teacher who is reading the poem by Wordsworth, which has the line 'splendour in the grass' in it, has her glasses in her hand, which then suddenly appear on her face.
