Michael Fassbender was almost in a band called Michael and Michael.

The Irish actor once harboured dreams of making it as a rock star and plays guitar, keyboard and sings in his upcoming movie Frank. He loved making music as a teenager, but was never organised to really try to make it big.

"I wouldn't call it a band," he told British newspaper The Guardian. "It was just me and another guy on guitar. We could never find a drummer or a bass player. We never even got as far as having a name. We were both called Michael so we could have been Michael and Michael."

Frank follows wannabe musician Jon as he joins a band called Soronprfbs, which is led by the title character - an unstable character who constantly wears a giant fibreglass head.

Michael portrays Frank and Maggie Gyllenhaal is his girlfriend Clara and wasn't put off by having to act opposite someone in a fake, expressionless, head.

"It's not entirely foreign to me. I've had experiences like that in my life," she deadpanned.

Maggie sings in the release and had to play a couple of instruments too, while on drums is Carla Azar who has played for Jack White in the past. French star François Civil joins on bass, with the group playing all the music featured themselves.

Michael isn't sure a record contract will be in the offing though.

"Somebody said one song sounded like Jim Morrison, but then the next one sounded like the Sex Pistols. We're never supposed to be good pop music, we're supposed to be odd music that strikes a beautiful chord in some kind of way, but remaining sort of… not shit music exactly, but let's say… hard to market," he laughed.
