The classic “dog and his pet boy” cartoon that appeared as part of the Rocky and Bullwinkle show will be appearing in 3D theaters as DreamWorks Animation’s Mr. Peabody and Sherman. Voicing the world’s smartest dog and his naive companion will be, respectively, Ty Burrell (Modern Family) and Max Charles (The Amazing Spider-Man). Rob Minkoff (The Lion King) will direct from a script by Craig Wright (Six Feet Under) which follows the duo as they attempt to restore order to historical events after Sherman uses Mr. Peabody’s time machine without permission. The voice of Mr. Peabody was originally supposed to go to Robert Downey Jr. (Iron Man), but I find Burrell to be an equally fitting personality for the inquisitive canine. Hit the jump for more on Mr. Peabody and Sherman, which is schedule to release on March 14, 2014.

Robert Downey Jr. is hopping in the WABAC Machine.  Entertainment Weekly is reporting that Downey will be providing the voice of Mr. Peabody in DreamWorks Animation’s adaptation of the Rocky & Bullwinkle characters Peabody and Sherman.  For those unfamiliar with the charming cartoon, Peabody was a highly-intelligent dog who would, with the help of his trusty boy Sherman, travel through time using the WABAC (pronounced “Wayback”) Machine.  The Lion King director Rob Minkoff will helm the film using a script from Yogi Bear screenwriters Jeffrey Ventimilia and Joshua Sternin.  For those worried that we’re in for another wretched CGI/live-action hybrid, you can put that fear to rest (as far as the medium is concerned).  Peabody and Sherman will be fully computer animated.  And like all DreamWorks Animation films, it will be in 3D.
