Yesterday saw both Hugh Jackman and Ryan Reynolds post an image of themselves along with Pierce Brosnan leading to speculation that possibly Pierce Brosnan could be playing Cable in Deadpool 2.
While Cable is often depicted in the comics as a ultra-jacked super dude, I wouldn't have a problem with Pierce Brosnan playing Cable at all.
Boss Logic put together the following fan art of Pierce Brosnan as Cable offering a more slender (and zombie?) look.
I think it could work.
