So Apocalypse will probably look pretty much like this, right? I've been assuming he'll be a CG mocap character; the vague unreality of even the highest-end CG could in this case work in the movie's favor to give him an even more nightmarish presence in addition to beefing up his physique.
Hopefully for the movie he'll have four belts instead of three

I always thought that was the most asinine character design for that game. He doesn't wear three massive belts on top of each other in the comics! He could never bend forward!

And while you're correct about making actors look bigger, there are limits, especially when it comes to brawling. It's a lucky thing for PJ and Co. that Tolkien never wrote a Frodo/Gandalf fistfight.
