Justin Timberlake has been in front of the camera since he was a child back on the Micky Mouse Club. So when he landed the role to play the voice of Boo Boo the Bear in the animated film Yogi Bear, he felt right at home. Apparently, he used to practice imitating the voices of iconic cartoon characters like Scooby Doo and many others as a child. Coincidentally, another one of those characters was Boo Boo. He would perform them for his parents to keep himself entertained and obviously, he was pretty good at it too.
