Cast of Halo Movie Chosen?

(I didn't feel like sending this in as a scoop as my email is funked, it has been for years, and my MSN is losing addresses at an alrming level. So I'll post it here to begin with as I'm not sure it's worthy of it's own movie thread...)

Well I found out for a certain site that some people are pictured to be playing parts in Halo already. Who? Well, as many sources have said Ridley Scott to direct, Samuel L Jackson as Captain Johnson (continuing his games appearances after his performance in GTA: San Andreas), and Ed Harris (a fabulous actor) as Captain Keyes.

Ok they aren't definate, but they are being pictured, imagine them now...
