Adding this to the above:
1.Given the meet-the-press history of Mr. Gibson's last two films (EDGE OF DARKNESS, THE BEAVER), it may take some huge behavioral remodeling for Mel not to either bristle at reporters' attempts to question/bait (EDGE) or opt for the specially-selected-"pet"-writer who will merely write down carefully-prepared PR responses (THE BEAVER).
2. I don't know if Mel's prepared to say something like this--"Hey, I'm in my mid-50s, and like many others in my generation, I grew up with prejudices about people with different religious beliefs and same-sex desires. And I acted like a bigoted fool and said hateful things in interviews and to everyday people as well. I'm sorry I've hurt people around me--including those I've loved and continue to love--and now realize that it's never too late to make changes."
3. Or this: "You know, I'm in my mid-50s, and I've not always been physically or verbally respecful when it comes to relationships with women. I want to avoid repeating my mistakes in the future."
4. Or this: "I'm in my mid-50s, and I'm aware the business is changing and may leave me behind. I'd still like a few big paydays, but I may have to get used to either a full-time career as director or playing occasional high-profile supporting roles like Russell Crowe is doing now as Superman's Superdad."
