At one point or another, every older male actor in Hollywood was rumored to be the frontrunner for the Cable role but, according to THR, Josh Brolin came out of nowhere and snagged it. So he’s Thanos AND Cable AND formerly Jonah Hex (wasn’t he almost Batman as well?)—that’s just greedy. I’ll bet they make a joke about it in Deadpool 2.
Seriously though—I get it. He has the right look and he will bring gravitas to the role. However, I thought Michael Shannon would have been good in the role as well. Hell, quite a few actors on the Cable list would have been interesting in the part. I’ll bet they make a joke about it in Deadpool 2.
