Leterrier sought Ray Harryhausen’s involvement, and reunited with Hulk concept artist Aaron Sims, who had already been working on Clash of the Titans with Norrington. Sims had difficulty designing Medusa, explaining "Are they all the same snake [in her hair]? Do they look more like hair? Are they different in silhouette or in light? And how much of a human face does she have, or is it more like a snake? ... I was working on one design, and people said "That reminds me of Voldemort," because there was no nose. You have to be careful so it still looks like it’s an original idea." Filming began April 27, 2009, in London at Shepperton Studios. Filming will also take place in Wales and the Canary Islands, primarily in Tenerife, while aerial photography will be conducted in Iceland, and Ethiopia.

Filming of volcano scenes at the Harriet hole in Dinorwic Slate Quarry in Wales wrapped at the end of July. This slate quarry has also been used for locations for Willow and Street Fighter.

A video game adaptation of the film is being developed by Game Republic and will be published by Namco Bandai Games America Inc. and Warner Bros. Interactive. The game will allow players to take the role of Perseus and follow a story based on the film. The game’s release is set to coincide with the theatrical debut.
