Michael Shannon is reportedly at the top of 20th Century Fox's list on who they're eyeing to play Cable in Deadpool 2. However, THR clarified that Shannon isn't quite a shoe-in for the role yet, as there are a few other choices for the character still in the mix, like Stranger Things' David Harbour. The article also notes that one factor that could prevent Shannon from joining Deadpool 2 is that he just signed on for the movie What They Had, which starts shooting in the spring. If Shannon were to be cast as Cable, this would be his third comic book movie role, previously playing Dr. Cross Williams in Jonah Hex and General Zod in Man of Steel.
