The latest single from Mumford & Sons second album "Babel" is "Hopeless Wanderer." And some truly superstar level talent was tapped to make the video. Namely Jason Sudeikis, Jason Bateman, Ed Helms and Will Forte.

In a typically melancholy Mumford song, these 4 take it to a whole new level. By the end they're grinding on stage, smashing banjos rock star style, and generally lifting the tone of the song to a strange and funny new level.
