Matt Damon has worked with some of the biggest stars in Hollywood, but in his latest role as a single dad who buys a zoo, he finds himself working with children and animals. So we had to ask, is it more difficult to work with little ones and furry ones, or Brad Pitt and George Clooney?
"Definitely Brad Pitt and George Clooney," Damon tells me on my HDNet talk show "Naughty But Nice." "It's similar, oddly. If a scene goes well, you throw them a treat. In George's case, it's vodka."
However, it's when his "We Bought A Zoo" co-star Scarlett Johansson compares Damon to a baby hippo that the actor really starts to speak his mind.
"I would be a baby hippo?" Matt asked me. "That is sweet. If Scarlett were an animal, what would she be ... Uh, a baby hippo -- bitch!"
But Damon does have someone on his side. Director Cameron Crowe said Damon would be a Lion -- something he agrees with: "See! He's got my back! No baby hippo bullshit!"
