Kevin Hart joked that he "hopped everywhere and ate nothing but grass" for seven months to prepare to voice a bunny in his new movie.
Hart stars as Snowball, the evil bunny in 'The Secret Life of Pets' and Kevin admitted trying to get into character was an unusual experience.
He quipped to Variety: "I spent time with bunnies for seven months. I didn't use my fingers. I hopped everywhere I went - ate nothing but grass."
Speaking about advice he got from the director Chris Renaud, he added: "Probably the funniest thing you can do about putting a small black guy in a small white rabbit's body is say, 'Be yourself.'"
Kevin loved playing the tyrannical bunny and worked hard to make him more sympathetic.
He explained to The Hollywood Reporter: "First of all, I'm a little crazy. Being that I got to play a villain, I said 'How do I make this villain a little complex? How do I make him full of levels and layers?' So I made him insecure, I made him emotional, I made him angry but all in all he's just a person that wanted love at the end. So I think to make your character likable is what's most important. Because when people like you they root for you, bad guy or no bad guy."
And Chris revealed his reasons for hiring Kevin, saying: "With a guy like Kevin Hart, who has this big explosive voice coming out of this little cute bunny, it just felt like it would be instantly appealing and fun."
