Despite being teased in the post-credits scene -- and promised for the sequel -- Cable didn't get to make his cinematic debut in the first "Deadpool" movie. However, the studio and creatives working on the project did discuss a possible Cable appearance -- but it turns out comic book co-creator Rob Liefeld, among others, fought against the idea.

Revealing that he wanted to hold off on Cable to give Ryan Reynolds a better chance to shine in the film, Liefeld told Inverse, "Half of us believed the movie should involve Cable. I could feel Cable breathing down my neck. I said, 'No. Don't put Cable in the first movie.' If Cable comes later, great. 'Deadpool' is a vehicle for Ryan to shine. Cable bogs it down, I'm not sure it works as a first film with a general audience. I got in the car and I said, 'Did I really just kill the appearance of my other more popular character?'"

"Deadpool" is currently in theaters. Its sequel, tentatively titled "Deadpool 2," is scheduled for a 2017 release.
