Stephen Colbert, Allison Janney, Ellie Kemper, Ariel Winter and Stephen Tobolowsky have signed on for Rob Minkoff's "Mr. Peabody & Sherman" at DreamWorks Animation says THR.
Based on the iconic cartoon series, Ty Burrell plays Mr. Peabody, the world's smartest being (and a dog). When he and his "pet" boy Sherman (Max Charles) use their time-traveling machine without permission, events in history spiral out of control and it is up to the duo to put things back on track.
Colbert will play Paul Peterson, Mr. Peabody's nemesis. Janney plays his wife, Paula Peterson, and Winter, their daughter Penny Peterson (the lovable bully who gives Sherman grief).
DWA has also moved up the feature by several months - from March 14th 2014 to November 8th 2013, swapping places with "Me & My Shadow".
