Ever hear a song and wish you were the person who wrote it? That’s the idea behind the new movie Yesterday, which imagines a world without the Beatles.

Yesterday stars Himesh Patel as a struggling musician who mysteriously wakes up in a world where the Beatles never existed. He then rises to fame by performing the Fab Four’s music as his own.

The first trailer was released on Tuesday, co-starring Kate McKinnon and directed by Trainspotting and Slumdog Millionaire director Danny Boyle. It even has a cameo by Ed Sheeran.

If you could travel back in time and take credit for something, what would it be? A hit song? Star Wars? The internet? Would you go for fame or wealth?
