Fox 2000 has assembled a cast of Greek gods for the fantasy adventure Percy Jackson, including Uma Thurman, Pierce Brosnan and Sean Bean, who have signed on to play Medusa, Chiron and Zeus, respectively, Variety reported.
Kevin McKidd (Poseidon) and Melina Kanakerides (Athena) are also joining the cast of the Chris Columbus-helmed movie.
The studio is still looking to fill the roles of Aries, Hades and Persephone. Logan Lerman and Brandon Jackson have already signed on to star.
The story centers on Poseidon's 12-year-old half-human son (Lerman), who embarks on a quest across modern-day America to save his mother, return Zeus' stolen lightning bolt and prevent a deadly war between the gods.
Shooting begins next month in Vancouver, Canada, with the studio setting a February 2010 release date.
