EXCLUSIVE: Olympus Has Fallen star Gerard Butler is in discussions to join Game Of Thrones’ Nikolaj Coster-Waldau in Gods Of Egypt, the Summit Entertainment film to be directed by Alex Proyas. The script was written by Burk Sharpless & Matt Sazama, the team behind Universal’s Dracula pic. I’m told Butler is in talks to play Set, a god of the desert, storms, and foreigners in ancient Egyptian religion. In Egyptian mythology, he killed and mutilated his own brother Osiris. Horus, the son of Osiris, sought revenge against Set for the killing of his father. Coster-Waldau will play Horus. They have both thrived in period macho turns, Butler in 300 and Coster-Waldau as Jamie Lannister in Game Of Thrones. Sounds like a good mano a mano match shaping up here if Butler’s deal closes. He’s repped by CAA and Alan Siegel Entertainment.
