Continuity mistake: Jesus is shown from behind on the cross with large gashes on the backs of his legs. He was flogged across the shoulders and back only at the pillar.
Factual error: Just after the start of the Korean War, McArthur places a map of Korea on the hood of a jeep to explain to a subordinate general his plans to invade Inchon. The map shows the boundary of North and South Korea not along the 38th parallel, which was the border at the time (1950), but along today's DMZ - not established until the Korean armistice was signed in 1953.
Continuity mistake: When Evel Knievel goes to the insane asylum to break his buddy Will out of the institution, he crashes through the front door with the Stratocycle, breaking off the airplane-style wings on each side of the bike in the doorway. In the next shot, as he rides down the hall, the wings are still intact.
