He and his adopted son Sherman have had all kinds of adventures in their time machine, but when Sherman starts school and finds himself teased by one of the girls, the pair of them have new challenges to overcome.
Mr Peabody invites the bully and her parents to dinner - and all is going well until Sherman decides to show her how the time machine works and she gets lost in Ancient Egypt, where she is set to marry King Tut.
Sherman and Mr Peabody set out to rescue her in this time-travelling adventure, which takes them to the Trojan War, Ancient Egypt and the Renaissance.
It's a fabulously funny film, with plenty of jokes for kids AND adults. This is one film you will all enjoy over half term - a family film that really does entertain the whole family. There are some neat running jokes, and towards the end it really does become rather 'Bill and Ted' like.
I have a feeling we will be seeing My Peabody and Sherman again in a sequel. The film is released on February 7, so make a date to see it over half term.
