Best action movie mistakes of 1970

Other mistake: When the Japanese planes take off for Pearl Harbor, some of the 3 man torpedo planes only have a pilot.

Deliberate mistake: There are no lights ever to be found in the underground world and the ceiling is literally the surface's ground, but there is still a perfect level of lighting regardless.

Factual error: In the movie you see Scottish Pipe Band playing. Pipe Bands where not established in Scottish Regiments before the Crimean War (1854-1856), there were only solo pipers. (00:35:00)

Factual error: During the scene where Clint Eastwood is trying to convince Don Rickles to join in the heist, there is a box of Almond Joy candy bars behind Don's head. They weren't introduced until 1946.

Plot hole: At the end of the movie, the sheriff is going home and gives his deputy and the mayor a ride home. They pass over a bridge with a sign that says 'Leaving Colusa County'. Surely they don't live outside the county?

Continuity mistake: The junkman played by Redd Foxx closes the door in front of the white guy, who gets in front of the broken window and shouts at him. His hand in the faraway view is on the sill, and in the tighter angle is at the side. (00:45:05)
