For Doom they would need to get a really seasoned and oscar winning actor this time - someone older too. Definitely not a second rate tv actor that's for sure. I remember when McMahon's name was in the hat for James Bond when Pierce Brosnan was being fired from his role and before Daniel Craig had been cast. I think he was once on Leno (or some similar show) and did his "Bond, James Bond" impression, and it sounded awful.
My own current pick to play Doom is John Noble, with the proviso that, yes, you likely need a younger actor for "Young Doom" scenes, and a very good stunt man inside the armor.
