Bruno Heller said that Xander Berkeley found out he was going to be Red John at "the last moment and he was thrilled" ... 

First question at the top of the page ...

"It's totally fair ... games over I won" - If that was the Sheriff's actual voice then he knew he was Red John the very first time that voice aired on the Mentalist years ago. How can you be on film doing Red John's voice and not know you are going to play Red John until "the last moment"! This means plain and simple .... that was not Xander Berkeley's voice or Bruno lied about when Xander found out and I see absolutely no reason to lie about that. If it was not his voice then Bruno Heller is not telling us one of a two things ...

1. Red John is not Sheriff McAllister
2. They had someone else do Red John's voice the whole time and Xander was lip sinking (If that is the case it's pretty poor planning but at least tell me who the actor is that does the voice out of curiousity ...

It just doesn't make sense. If Xander really did the voice then he knew for years and if he didn't do the voice then wtf who did? I really don't think this adds up ... Have there been any interviews with Bruno Heller about the Red John voice?
