A character name change led to a key scene being re-shot in 1977 "Star Wars: Episode IV - A New Hope". Mark Hamill revealed that the famous Princess Leia rescue scene from 'A New Hope' had to be re-shot because his name was changed from Starkiller to Skywalker.

"The name change to Skywalker came late enough in production that we had to re-shoot the scene where I liberated the Princess from her cell," Hamill tweeted. "We had already shot it using the original line: 'I'm Luke Starkiller, I'm here to rescue you!'"
