Based on the 1959 US four-and-a-half minute broadcast skits, "Peabody's Improbable History", the film is a father-son bonding adventure film laced with history and time-travel.
From the stable of Rob Minkoff, who had earlier directed "Stuart Little" and "The Lion King", "Mr. Peabody and Sherman" is a light-hearted emotionally manipulative film where a super-intelligent talking dog adopts a boy, rears him and educates him in a unique manner on how important events actually happened.
The first twenty minutes of the film explain how, through a judicial precedent of a cross-species adoption, Mr. Peabody (Ty Burrell), a highly intelligent, multi-faceted dog, gets to father the orphan human Sherman (Max Charles).
