Hold on. Hear us out! The X-Men series has always carried its films on the backs of very "serious" actors -- three Oscar-winners and counting. With that standard in mind, Crowe could do for the film what he did for "Man of Steel" and really class it up. Hugh Jackman's ties to his "Les Misérables" co-star wouldn't hurt in courting the Oscar-winner, should the studio go that route, and since they're likely going to motion capture Apocalypse anyway, it would be easy to see Fox pull a Thanos/Brolin and have Crowe serve as the voice for mutantkind's doom.
