DreamWorks Animation has released a new trailer for Mr. Peabody and Sherman, arriving in theaters March 7. Modern Family star Ty Burrell lends his voice to Mr. Peabody, with Max Charles voicing Sherman, who must go back in time to rewrite history, after Sherman shows classmate Penny (Ariel Winter) their time-travelling device, the WABAC Machine. Take a look at the latest footage from director Rob Minkoff's animated adventure, which shows that Mr. Peabody was actually the inventor of the fist bump and planking.
