ELI5: How were movies edited before the invention of the computer?

Especially movies like King Kong. My mind is boggled at people able to edit king holding a person in his hand without a computer.

Movies used to be shot on 35mm film. Directors & editors would view everything that was shot. They would cut the films apart and splice together what they wanted. The rest was discarded, or saved for later. This is where the expression ''Left on the cutting room floor'' came from.
