Ocean's Eleven (1960)

Factual error: When one of the men visits a doctor and learns he is terminal, the X-ray in the scene is upside down.

Character mistake: In one scene, one of the people suggests that Danny Ocean should run for President, and the first plan of action was to repeal the "13th and 20th" Amendments to the constitution, allowing women to lose the vote and go back into slavery. The 20th Amendment has nothing to do with women's right of voting, that is the 19th Amendment. If the 20th Amendment were repealed, the President would again take office on March 4th in the year following the election.

Character mistake: When one of the men visits his young son at a military school and then leaves, the outdoors background scene shows two cadets passing each other. One of the cadets salutes the other with the left hand.
