Atlantis will return to BBC One next month.
The fantasy drama will resume its second series on Saturday, April 11 at 7.45pm.
Based on the Greek myths, Atlantis was cancelled by the BBC earlier this year, but returns to air its final seven episodes.
Series star Jack Donnelly - who plays Jason - previously told Digital Spy that he was "gutted" by news of the show's axing.
"Everything is left up in the air - everything," he said. "I think the ending is brilliant, but they really set it up - the producers definitely had an idea for what the third series was gonna be.
"We'd had massive discussions - me and the other actors - about what might happen and that's all left up in the air."
