Continuity mistake: When Marty chases after Biff on the borrowed 'skateboard', Marty is wearing a dark grey belt and a red/blue print shirt under his red/beige jacket. However, when Marty is hanging on to the front of Biff's car as they turn a corner (and in another shot), Marty (stunt double) is wearing a light brown belt and solid tan shirt.

Trivia: Eric Stoltz was originally cast as Marty. After filming quite a few scenes they realised his acting style was too dramatic for the humor desired, so they cast Michael J Fox (who they couldn't originally get because he was busy with the TV show Family Ties). Filming was on weekends and nights around his TV schedule and using his double at other times.Stefanie
Question: Can you please explain to me how Doc got into the DeLorean from within the truck? Clearly the internal width of the truck is not capable of handling gull-wing doors whilst parked inside. He would have had to push the car out, get in, drive it back in, then remotely close and open the hydraulic door/ramp on the back of the truck. This is one of the things which really sticks out in the film for me.
