According to Contactmusic, the singer, who will star opposite Dan Aykroyd in Warner Bros' live-action/CGI movie, has revealed that he is honoured to be a part of the project because he watched the cartoon as a child.
The 28-year-old said: "It's pretty awesome. I used to watch the cartoon as a kid. You're talking about a classic, two classic characters which have been around since my parents. Yogi Bear is an iconic Hanna-Barbera cartoon. So it's been a lot of fun."
Timberlake also admitted that he and Aykroyd will promise fans that they would stay as true to the characters as possible, adding: "I will say this, Dan does an amazing Yogi Bear and hopefully I did Boo-Boo justice.
"But we're really - for lack of a better term - mimicking what you recognise as those voices from the cartoon."
