Take another hit on that crack pipe.
I think he means, Dean would have turned out to be like Brando -- basically, a sad, pathetic mean individual -- had Dean not mashed himself in that car wreck and died so young.

LOL!
Although in doggy-years he was old...
I don't smoke crack, never have. I understood alloysteel to mean that, if Dean had survived into old age, he may have turned out quite a bit the way Brando did. I think that's true. I think Dean would still have played great characters and I think his personal life would have been a train wreck.
