Mumford & Sons release a music video for their song 'Hopeless Wanderer,' and aside from the open field shots, fans of the band will notice something very different. Jason Sudeikis, Ed Helms, Jason Bateman and Will Forte parody the band's famous folk style in the hilarious video, right down to Sudeikis as Marcus Mumford with a tiny moustache. Kristina Behr has a look.
