Michael Fassbender was having such a hooley at the after-party for his movie A Dangerous Method (the one where he spanks Kiera Knightly, yaddah, yaddah) on Tuesday night that he was asked to leave.

The 34-year-old actor was in "good spirits" as he celebrated at Mayfair restaurant 34 following the London premiere of the film but following antics including dancing/dipping his co-stars Keira Knightley and Viggo Mortensen around the room, taking over the venue's piano and finally lighting up a cigarette, he was asked to leave.

Speaking about Michael - who was carried out of the party on his friend's back - a source told The Sun: "Michael was politely asked to leave. He was in good spirits but it was becoming a bit of a handful for the other guests. He was grabbing his co-stars and waltzing around the room with them. He lit a a cigarette indoors and that was the point it had gone too far. He's a great actor and women loved him in 'Shame'. It might have something to do with him having his todger out for most of the movie."

Michael's co-star Keira has previously revealed the pair got through the more uncomfortable scenes in the film - which include Michael spanking her - by horsing the hooch into them.

Keira said: "We only had one or two shots maximum. It was a vodka shot to calm our nerves and away you go really. Then we had champagne. We drank quite a lot of champagne actually. You can count on Michael to buy a bottle of champagne when one is required. The vodka and champagne is a good combination."
