Gibson Actually Considering Returning For "Lethal Weapon 5"?

It's been rumored that actor, Mel Gibson is finally considering stepping back into the role of Martin Riggs for a new fifth outing in the "Lethal Weapon" franchise. Gibson thinks that this could reboot his film career after he has lost is fans and the general public hate him after his little angry phone call to the mother of his child, Oksana Grigorieva.
He probably thinks that if he does this, he will win back his fans. I don't really care about the guys appearence in the public eye, all I really care about is him doing a fifth "Lethal Weapon".
Supposedly, he's been meeting up with Joel Silver, producer of the "Lethal Weapon" franchise. Now why would you be meeting up with the producer, if you weren't discussing a new sequel.
Gibson is only 54, he can still do a fifth film. Ok, Glover is 63, but he can still do it as well. Look at Sly. He's 64 and he's still kicking ass on-screen and so is Harrison Ford. He's coming back for "Indy 5" soon. Obviously, all we can do is take this as a rumor. But I'll keep everyone updated on this news as it comes in.
