Mel Gibson has gone back to work on his next film amid rumours that he was violent in his relationship with Oksana Grigorieva.
Gibson is working on The Beaver, where he is playing a nut case who communicates through a hand-puppet.
According to sources, the $20 million comedy, directed by Gibson's friend Jodie Foster, was shot last fall but didn't test well. So he did re-shoots in New York.
"Mel was in complete shock. Everyone was walking on eggshells around him. It was the weirdest set ever." The New Post quoted an insider as saying.
