Other mistake: This takes place in 1942, but modern 1970s era cars can be seen behind Wonder Woman and Steve when the attendants are loading Benson into the ambulance. Then again later, when The Falcon's partner creates a diversion and is being shot at by the guard.
Continuity mistake: When Wonder Woman chases after Benson her boots are flat and then the heels appear. It happens again later, while The Falcon tries to reach Professor Warren.
Visible crew/equipment: When Diana and Steve meet with Dr. Barnes at the hospital, they stop in the corridor to discuss the guard's condition, and when they resume walking the actors' T-mark and two tape marks are visible on the floor, where they had been standing.
