"Anyone could be Mad Max . . . that was the point."
Speaking of anyone being Max, I just don't see how Ledger would have pulled off the role in Fury Road. I guess his death was TDKR's loss and FR's gain.
As for the movie as it stands, he clearly wasn't the Feral Kid. In the opening voice over he says he was a cop then a road warrior. If that doesn't describe Mel's original path I don't know what does. Plus the opening credits list him as "Max Rockatansky" not some generic "Mad Max" that anyone can be.
