Who could forget the Pythagoras theorem? Sure didn't we chat it from Maths classrooms in the far corners of the island eh? Anyway, that fella there yonder is Robert Emms, and he's just been snapped up by the Beeb to play Pythagoras himself (may just be a common name though...) in new Saturday night fantasy drama, Atlantis.

This young fella just so happened to star in Broken with Tim Roth, and if you read our review then you'll know just how impressed we were with his performance. Could this be a major casting coup on the BBC's behalf? It bodes well for the new series in our eyes anyway...

If you missed our little preview of what the Beeb has to offer in 2013, then here's the lowdown. "The city of Atlantis is a mysterious, ancient place; a world of bull leaping, of snake haired goddesses and of palaces so vast it was said they were built by giants", the official blurb reads. "It's into this strange, compelling realm that the young Jason arrives and an amazing adventure begins, bringing to life the vast store of Greek myths and legends re-imagined for a new generation."

There's still no word on the mysterious 'Jason'. Emms is the first actor to be cast in the magical drama, which BBC Controller Ben Stephenson claims will fill the void left by the lads from Camelot. Ah heyor now Ben, them are strong words so they are.

Atlantis starts shooting in in Wales and Morocco from April, with the 13 part series is expected to hit our screens later in the year.
