Continuity mistake: In the end sequence, where willy jumps the wave-breaker/jetty, in one shot Jesse is on the wave-breaker, in the next shot, where willy starts the jump, Jesse's gone. In the next shot Jesse's back.
Visible crew/equipment: At the end of the film when Jessie is saying his last words to Willy, when the camera is looking at Willy in these shots you can see the entire boom mic and pole reflected in Willy's wet skin.
Continuity mistake: The sky at the end changes several times from being cloudy to clear. Look at the reflection of it when Willy comes over to Jessie in the water. The next shot is cloudy. The jump scene is clear, and then it is sunny.
