Cable, the fan-favorite time traveling mutant, made his first cinematic appearance in Deadpool 2, but director Bryan Singer almost included him in his film, X-Men: Days of Future Past. And he almost died.
In a recent interview, Rob Liefeld, the creator of both Cable and Deadpool, revealed that, rather than Bishop appearing as one the future X-Men, Cable was supposed to appear.
"He was originally in Days of Future Past in the Bishop role and he got killed," said Liefeld in an interview with ScreenRant. "And then there was a note that came back that said he's kind of too big of a character to do this with, and poor Bishop got slaughtered instead. But I swear to you... So, summer 2012, I was like, you can't, you can't have Cable. Like, as much as I want to see him, fans will freaking go nuts if they see him and you kill him immediately. He's too big."
Bishop in X-Men Days of Future Past is presented as a subtle side character. Much of the lore and characterization that made him a fan-favorite is ignored in order to put the focus on the core characters of the film. It seems as Fox believed Cable was destined for bigger things.
It is unknown if Josh Brolin would've played the character had he appeared in Days of Future Past.
