Sofia Coppola wrote the lead role specifically for Bill Murray, and later said that if Murray turned it down, she wouldn't have done the movie.
Sofia Coppola wasn't sure if Bill Murray was actually going to show up for the film. Murray works without a management, and according to Coppola, he had only given her a verbal confirmation. While production was being set up in Tokyo with no sign of him, she started to get nervous, but was assured by Wes Anderson (who had directed Murray in Rushmore (1998) and The Royal Tenenbaums (2001)) that Murray was a man of his word. It was indeed when Murray landed in Tokyo one week before filming that his participation was ensured.
Francis Ford Coppola, Sofia Coppola's father, urged her to shoot the movie in High Definition Video because "it's the future," but she chose film because "film feels more romantic."
The entire budget for the film was $4 million. It grossed $44.5 million in North America, and $119.7 million world wide.
