It’s not easy being the world's smartest and most brilliant dog. In fact, it’s pretty darn difficult. Mr. Peabody is taking his endless adventure pallet onto the big screen, with a time-travelling yarn through ancient Greece and Egypt.

Mr PeabodyMr Peabody urged Sherman not to use the WABAC

Ol’ Peabody would probably just be sitting around playing scrabble with young Sherman now, if the scamp didn’t have designs on impressing the equally yong but more mischievous Penny Peabody.

Of course, a trip in Mr Peabody’s ingenious WABAC (pronounced “way back) is what she wants to do, and a smitten Sherman obviously obliges. The troublesome twosome manage to rewrite the annals of history: Sherman loses Penny in ancient Egypt, Penny gets engaged to King Tiyi and they run out of gas in ancient Troy.

Mr Peabody and ShermanAnd what did he go and do...?

“Oh dear” indeed, Mr. Peabody.

The film sees Modern Family stars Ty Burrell and Ariel Winter combine as Mr. Peabody and Penny respectively, while the remaining all star cast consists of: Leslie Mann, Allison Janney, Mel Brooks and Stanley Tucci.

Reports suggested that Iron Man’s Robert Downey Jr. was to voice the part of Peabody, but Burrell replaced him in March 2012. The film, which is produced by Alex Schwarz and Denise Cascino, and written by Craig Wright, has been subject to many delays and initially set for release in October/November 2013.
