Nobody really asked for a 3D film version of the Yogi Bear cartoon that features the vocal talents of Dan Aykroyd or Justin Timberlake – but that is exactly what moviegoers will get this December.

A second trailer has been released for Yogi Bear, the titular star who made his debut as a side character on the cartoon The Huckleberry Hound Show back in 1958.  The picnic-basket-loving bear was given his own TV series three years later and has since become one of the most famous characters created by Hanna-Barbera Productions.

Fast forward to 2010 and now Yogi Bear (voice of Aykroyd) and his companion Boo Boo (Timberlake) have been brought to life in a motion picture via the magic of modern-day computer technology.  Joining the animated critters in the film will be flesh-and-bone performers Tom Cavanagh (a.k.a. Zach Braff’s brother on Scrubs) and Anna Faris (star of the Scary Movie franchise).

The plot of Yogi Bear revolves around a ploy by an evil mayor who is out to shut down Jellystone Park and the subsequent efforts of Yogi, Boo Boo, and their old nemesis Ranger Smith (Cavanagh) to try and save the beloved forest.  Not that any of this can be gleaned from the new trailer, but really, it is for a Yogi Bear movie – we should just be thankful it contains only one “bears passing gas” joke.

Check out the second official trailer below:

The film looks pretty harmless, all things considered – yes, this is a show for the kiddies, but for the most part the footage released so far has consisted of inoffensive gags involving food, comical pratfalls and Cavanagh playing the straight man opposite his not-very-convincing CG co-stars, a la Jason Lee in the Alvin & the Chipmunks movies.  Hey, it can’t be any worse than those were, right? :-P

Will Yogi have the same success at the box office as Alvin, Simon and Theodore did?  The former’s movie is being released at the beginning of the winter holiday season and aims to appeal to the same family crowd that flocked to check out the Chipmunk’s (sigh…) Squeakquel around the same time last year.  Warner Bros. can only hope that not all moviegoers opt to see Tron Legacy instead.

Yogi Bear arrives in 2D and 3D theaters in the U.S. on December 17th, 2010.
