Talking at Comikaze, Rob Liefeld revealed that he advised Fox not to include Cable in Deadpool's solo outing (explaining why Colossus was in early drafts of the script as a second lead of sorts) and that he shared many ideas with them following the character's disastrous debut in X-Men Origins: Wolverine. "Following Wolverine, the Donners called me into their office and said, ‘Rob, we want to meet and talk to you about Deadpool, since we’re spinning it off. We know we made some missteps, and we want to get it right.’ So I sat there with a bunch of producers, and we sat for several hours, and we talked about different ideas. And I tried to steer them in directions I think. For instance, I’ll tell you, first question they said, ‘Rob, does Cable need to be in the Deadpool movie?’ And I said, ‘No, Deadpool deserves his own function and Cable should come in in his own movie.’ And they were like, ‘Ok, because we were thinking about…’ And I was like, ‘No, you can do them both separately. They don’t need to be in the same movie.’ Look, we had a long talk, we had some ideas, I can’t share them, some of them made it across the finish line."
There's a lot more in the video above, including Liefeld's thoughts on the writers of the Deadpool movie, what it was like to see the leaked test footage, and Fox's reaction to that ("We have computer forensics. We will find that person..."). He also singled out Ryan Reynolds as playing the character and pointed to his passion for the project as being the main reason it's finally happening. "Ryan is Deadpool. Look, Ryan Reynolds, he’s gone through that same career arc, the guy is ridiculously talented. He has a huge, huge passion for Deadpool. Deadpool’s not happening, because he was a giant star, they said, ‘Ryan, what do you want to do?’ And he said, ‘Deadpool.’ That’s why it happened. They would have no faith otherwise. That movie is because of his passion. He put together the team." As for when and if Cable will make his big screen debut in the near future, all he would say is: "Cable is awesome. And he will…when he appears on screen, we’re all going to nerdgasm, because he’s coming. They can’t hold him back. He’s coming."
Yeah, he created these characters, but they're totally owned by Marvel. And beyond that, I think Cable is essentially what Liefeld created him to be, but if other, far superior writers didn't come along after Deadpool he would just just been another forgettable nobody character from the early 1990s. So, I'm not sure why execs would be consulting him over some funnier, better writers who handled him over the years (i.e., just about anyone else who wrote for the character).
