Don't feel bad for Michael Fassbender, who was left out of the Best Actor Oscar race despite his critically-acclaimed turn in Shame.
He appears to be in very good spirits.
The Irish actor, 34, was photographed Tuesday having a grand ol' time at the London afterparty for the premiere of his new film, A Dangerous Method. Fassbender was snapped taking a turn at the piano and dancing with his costar Keira Knightley – and Viggo Mortensen.
The night got so crazy that he made an unorthodox exit from the GQ-hosted bash, reports The Sun tabloid.
