Just in case you thought it wasn't Michael Fassbender belting out the tunes and busting out the moves in Lenny Abrahamson's Frank, he and his fellow castmates inluding Maggie Gyllenhaal and Domhnall Gleeson took to the stage at the afterparty for the New York premiere of the film last night and showed the world what they were made of.

Whereas everyone here got their eyes on Frank months ago, it's only seeing US release this month, and as such Fassbender and the rest of the cast have been on the rampage trying to get our western neighbours to check out their bizarre indie movie.

And of course it was all caught on people's iDevices and such and uploaded to Instagram for our consumption. We'll leave the judgement to you.
