The cast of Greek gods for the fantasy adventure Percy Jackson have come forth with Uma Thurman, Pierce Brosnan and Sean Bean to play Medusa, Chiron and Zeus, respectively. Kevin McKidd (Poseidon) and Melina Kanakerides (Athena) are also joining the celestial bunch in the film to be directed by Chris Columbus.

More roles need to be filled which are Aries, Hades and Persephone. Logan Lerman and Brandon Jackson have already signed on to be the stars.

The godly story focuses 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.

Filming starts next month in Vancouver and a February 2010 release date.
