GRAND RAPIDS, Mich. (WOTV) A character known as part of the Rocky and Bullwinkle Show is now getting a movie of his own. “Mr. Peabody & Sherman” features Mr. Peabody, a genius and the world’s most renowned dog, and his adopted son, Sherman. Mr. Peabody invents a time machine and, against his wishes, Sherman uses it to try and impress a friend. The movie is a great story about parent-child relationships and offers some lessons about consequences. “Mr. Peabody & Sherman” is rated PG for some crude humor and action. It opens Friday, March 7, and is showing in 2D and 3D at Celebration! Cinemas.
