The BBC's take on Atlantis is of a mysterious, ancient place with vast palaces said to be built by giants, snake-haired goddesses and other mythical creatures. The drama's main protagonist, Jason, is a young man who arrives on Atlantis and begins a series of adventures.
The show will be shot in Wales and Morroco, with filming due to begin next month.
Atlantis has been written by Howard Overman ( Misfits, Merlin , Dirk Genty ) and is being produced by Julian Murphy and Johnny Capps ( Merlin ).
