Continuity mistake: Eddie drives a 1957 Chevy convertible off the bridge. A scene showing the car being fished out of the water clearly has an older vehicle dangling from the line.
Suggested correction: The car pulled onto the bridge is absolutely a 1957 Chevrolet convertible.
Continuity mistake: When Eddie and Joann leave Satin Records they get in the car and there's a rear-view mirror on the windshield, but it vanishes while they're driving, and then it reappears.
