WATCH: Mumford & Sons unveil new video

Stadium-folk quartet Mumford & Sons have enlisted the help of a host of famous funnymen for their new video.

Arrested Development's Jason Bateman, The Hangover's Ed Helms and comedians Jason Sudeikis and Will Forte all play members of the London band, basically taking the mickey out of their rootsy, po-faced image. Watch it below.

'Hopeless Wanderer' is the latest single taken from last year's Babel.
