Actor Idris Elba arrives at the 19th Annual Elton John AIDS Foundation's Oscar viewing party held at the Pacific Design Center on Feb. 27, 2011 in West Hollywood

*Idris Elba will join Sean Harris and Kate Dickie in the cast of Ridley Scott’s sci-fi epic “Prometheus,” according to the director himself via The Daily Mail.

Scott also confirmed the previously announced casting of Noomi Rapace, Charlize Theron and Michael Fassbender and revealed that the actors, who’ve all signed secrecy clauses, were only allowed to read the script at Ridley’s production office.

Asked about the plot, Scott says “It’s the story of creation, the gods and the man who stood against them. It’s not a small film.”

Shooting begins in three weeks across seven soundstages at Pinewood Studios in Toronto.
