Nearly a year ago, Robert Kirkman was interviewed by MTV about the possibility of Jon Hamm (Mad Men) being cast as fan-hated villain Negan on the The Walking Dead television show. Kirkman responded that:

"He’s not tall enough! That’s a joke. I think Jon Hamm would be perfect. I think after “Mad Men” has run, Jon Hamm is going to have a Tom Hanks level film career, so I don’t think he’ll be coming back to television anytime soon. Although that would be cool!

As far as Negan casting goes, Scott and I are always talking about who we would put in that, it’s definitely on our minds, and there are definitely a lot of candidates. But I wouldn’t expect Negan too terribly soon, although he is definitely in the plan. It’s a 99% lock that he’s going to be in the show eventually, so be on the lookout for that."

We now have a video interview courtesy of MTV of Hamm on the subject of coming on to The Walking Dead as Negan.
