The LA Times has an interview up with Daft Punk about creating the score for Tron: Legacy. It’s really interesting, but even cooler is when they were asked about their famous robot helmets and if they were inspired by Tron:
So it had to be asked: Are those robot helmets (without which Daft Punk is never photographed) an implicit homage to â€œTronâ€?
â€œItâ€™s closer to a â€˜Star Warsâ€™ vibe,â€ said De Homem-Christo. â€œItâ€™s very ’70s, but very relevant to me. We are robots, because we think it fits.â€
So there you have it, Daft Punks signature look was inspired by Star Wars.
