The peculiar life of musician Frank Sidebottom comes to life on the big screen this weekend with the new indie comedy Frank. To help get fans ready for this unique experience, we have an exclusive TV spot which shows some of the nation's critics offering big praise for director Lenny Abrahamson's adaptation of Jon Ronson's book.

Although you can hardly tell from the footage, Michael Fassbender stars as the title character, an eccentric music genius whose identity is concealed by a massive paper mache head that he wears at all times. Domhnall Gleeson, who also stars in next year's highly-anticipated Star Wars: Episode VII, plays a young musician who joins Frank's band. Take a look at the new footage before Frank opens in limited release August 15.

Frank is a comedy about a young wannabe musician, Jon, who discovers he's bitten off more than he can chew when he joins a band of eccentric pop musicians led by the mysterious and enigmatic Frank and his terrifying sidekick, Clara. Frank's uniqueness lies in the fact that he makes music purely for the joy of creating...and because he wears a giant fake head. After a rocky start, Jon ingratiates himself with the band members, and they retreat to a cabin in the woods to record an album. As his influence waxes, creative tensions mount, and the band's entire raison d'être is called into question.
