Michael Fassbender was ejected from the London premiere of A Dangerous Method after becoming unmanageably drunk and making an a** of himself.

The 34-year-old is apparently a very happy drunk, and was enjoying himself just a little too much at 34 restaurant in London on Tuesday night, at one point hijacking the restaurant's piano. According to a witness speaking to 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 cigarette indoors and that was the point it had gone too far.

Fassbender was carried out of the party on his friend's back. The actor was photographed smoking cigarettes outside the venue and at one point flipped the bird at paparazzi - smiling the whole time, of course.

The German-born actor, who was raised in Ireland, plays Carl Jung in the A Dangerous Method. He was nominated for a Golden Globe for his performance in Shame, where he appeared nude.

Celebitchy and The Mirror have some pretty hilarious photos of the afterparty.
