I read somewhere that Denzel Washington was once considered for the role of the Master Chief, and that the helmet would have a transparent visor, rather than the shimmering gold one we all know.
While I think Washington is a good actor, he would be at the bottom of my personal list for people who play that role. He just wouldn’t be the right guy for the job.
Heaven save us if they try to sneak in a CGI stretched Tom Cruise.
Obviously a no-name actor, but someone much like a Rutger Hauer person would better, first off it has to be a personna of what the MC is both physically in size and with the hard core dedicated warrior mindset, of which Hollyweird seems to have lost.
