It's now less than two weeks until the return of The Walking Dead and even though we won't see The Governor until season 3 (at the earliest) there are already speculations on who will be play him. In an interview with Movieweb Tom Savini says he's ready to step in and do the role but that the creators of the series are looking to have John Hawkes play The Governor. And for those of you that doesn't follow the comic version of The Walking Dead I can tell you that The Governor is one of the cruelest characters I have encountered.
And here is an interview with Robert Kirkman (creator of the comic) and Glen Mazzara (showrunner for the TV series) about season 2.
