Well, it really isn't difficult trying to figure out what Joseph Gordon-Levitt would have wanted to be if not a film star. The Dark Knight Rises actor showed his music talent once again this past week in front of a full crowd at the Sundance Film Festival. This time he did a cover of the Beatles hit "Hey Jude."

Strumming on his guitar isn't new to Gordon-Levitt. He's previously performed and uploaded a video with friend and 500 Days of Summer co-star Zooey Deschanel.
