I’m an animal lover who has a really hard time with people joking about animal cruelty. I was absolutely terrified by the movie Ratatouille because the poor rat kept getting into dangerous situations and making me worry about his well-being, even though he was fictional. I can’t laugh at the cat lady on the Simpsons who often waves her yowling cats around by their tails. But I thought this was funny. He knows that the bear gets (and deserves) special treatment and was just speculating what it might be like if human actors were treated like animal actors. I am sure that, if the animal plays a major role in the movie, they are treating him very well, and jokingly comparing him to a demanding human movie star is all in good fun.
