All the more depressing when I have seen Gibson himself claim he'd be up for doing a fourth Mad Max film. What a waste. 
if he was serious he could have signed up for Mad Max 4 pretty much anytime over the last 8 years or so when the project was developing. If this CGI flick gets made it will because they'll be using the script that's already been developed for a never made Mad Mad 4, not a new one for this project specifically.
That this is being made at all seems to signify that George Miller is ready to give up on the series altogether, make something out what's already been done and put it all to rest. I thought the
Mad Max game would use the leftover story materials from MM4, but I guess its doing its own thing or whatever.
