O Brother, Where Art Thou?

This 2000 crime-comedy stars George Clooney, Holly Hunter, John Goodman, John Turturro, and Charles Durning. The storyline begins in 1937, and follows three ex-convicts hot on the trail of a buried treasure in southern Missouri.

One scene set in a movie theater contains the glowing interruption of a modern-day exit sign, something that would have not existed in any 1937 building. This prominent intrusion has many of us scratching our heads.
