O Brother, Where Art Thou?
This Coen brothers 2000 crime comedy-drama is meant to take place in 1937, but there was one major malfunction when it came to set design. During one scene, a neon "EXIT" sign can be seen in plain view toward the back of the theater. A little ahead of its time, don't you think?
John Wick
John Wick became the first installment in an ongoing series, but it wasn't without its flaws. In the beginning of the 2014 film, Wick (Keanu Reeves) encounters a trio of Russian gangsters at a gas station in New Jersey who ask to buy his car. However, it's illegal to pump your own gas in New Jersey, meaning that in all likelihood, the encounter would never have taken place.
