A woman in a pink-and-orange jacket, baseball cap and bathing suit walks by in the background in several scenes, (sometimes back and forth in the same one).
Twice when Catherine stops to catch her breath - on the beach and when she's rollerskating - her right hand jumps from her side to her chest between shots.
When Hobie is putting newspapers under the boat, a pair of bikini-clad girls (one in white shoes, one in black boots), can be seen to loop back and forth in the background.
