Days of Thunder (1990)

Revealing mistake: When Tom Cruise and his girlfriend are visiting his former arch rival and now good friend, his wife calls Tom "Tom", not by his character's name.

Continuity mistake: When Harry is telling Cole to "Run 50 laps your way, then run 50 laps my way and I'll beat you every time," Harry is at first wearing a Georgia bulldogs baseball cap. Then a Florida Gators hat when he leans in the driver's window. Moments later when he speaks to Cole over the radio after the test run has started, he's now wearing a Georgia Bulldogs hat again.

Plot hole: I have never seen a Daytona 500 race where the winner is immediately left completely alone and is able to walk over to his crew chief who is still at the pit wall and hold a quiet conversation.

Trivia: The scene where Tim approaches Harry at a tractor was filmed at the farm of NASCAR legend Junior Johnson.

Tim Daland: I had sponsors in from all over the coast and I'm hugging, and holding hands, and praying for a good showin'. And what do we do? We end up looking like a monkey fucking a football out there. Everybody out, please.

Harry Hogge: Cole, you're wandering all over the track.
Cole Trickle: Yeah, well this son of a bitch just slammed into me.
Harry Hogge: No, no, he didn't slam you, he didn't bump you, he didn't nudge you... he rubbed you. And rubbin, son, is racin'.

Dr. Claire Lewicki: Boy, you're very quick.
Cole Trickle: You oughta see me drive.
