Revealing mistake: When The Wraith is parked at the convenience store, wet tire prints are seen on the concrete from previous takes of the car backing up and turning off the store's lot. This is confirmed later as Charlie Manx actually reverses the car when he drives off the lot.
Revealing mistake: Multiple times when we see the speedometer of the minivan, the RPMs aren't moving. The car's shifter is also noticeably in park. This is obvious as its higher, whereas if were in drive, it would be lower. Even during the most intense moments, the RPMs never change. The car is obviously being towed by a camera vehicle.
