Iron Man star Robert Downey Jr. has agreed to be the voice of gifted dog Mr. Peabody, in the 3D animated film Peabody and Sherman, reports Entertainment Weekly.
These are characters from old popular television shows for children Rocky and His Friends and The Bullwinkle Show.
“Certainly for boomers, they’re in the sweet spot of our childhood animation memories, but beyond there it gets a little bit, well, not quite as familiar,” said director Rob Minkoff (The Lion King).
Downey will voice the super-smart bespectacled dog Mr. Peabody who adopts a pet boy, and together they travel through time to discover some interesting moments in history.
Joshua Sternin and Jeffrey Ventimilia will write the script and the film is schedule for release in 2014.
In the meantime, Robert Downey Jr. is currently filming Sherlock Holmes 2 set for theatrical release this coming December. Then he will start filming The Avengers in which reprises his Iron Man role. The film is slated for theatrical release May 4, 2012.
