Matt Damon welcomed a special costar onto the set of We Bought a Zoo in LA yesterday. He was in front of the cameras with a huge grizzly bear, but the actor was safely inside a car for the scene. Matt's getting back to work on his wild movie after taking a break to promote and release The Adjustment Bureau. The action film didn't get a lot of love at the box office, but we enjoyed all of Matt's press stops like his hilarious appearance on The Today Show. He also shared some sweet love advice as he made the rounds and showed off his own happy relationship at the Valentine's Day premiere.
