Last week, we reported that production is under way on the Marvel Phase Two ensemble Guardians of the Galaxy at Shepperton Studios in London. Today, Dave Bautista, who plays Drax the Destroyer, released the first photo from the set, featuring the actor submerged in a tank of water. The actor also mentioned Namor in his tweet, the mutant son of a sea captain and a princess from the underwater city Atlantis from the Marvel comic books. This is the first time we've heard the character, also known as Namor the Sub-Mariner, being mentioned in Guardians of the Galaxy, so it isn't clear if the actor is describing an actual character in the movie, or just joking about the underwater shoot. At any rate, take a look at the photo, along with a description of his chat with director James Gunn.
