According to the Hollywood Reporter, Shannon is the frontrunner, though not the only name on the list. "Stranger Things" star David Harbour is also a candidate, though Kyle Chandler -- thought rumored for the role -- is not.
In the comic books, Cable, aka Nathan Summers, is a mutant with telepathic and telekinetic powers. He is also the son of Scott Summers aka Cyclops. The character is depicted as bulky and strong, with an intimidating presence. Cable was often paired with Deadpool in comics, and his inclusion in the sequel was teased both at the end of the first movie and in an Easter egg in "Logan."
If Shannon is selected, he'll join Reynolds and new "Deadpool 2" cast member Zazie Beetz, who is playing the mercenary Domino.
