the greatest ? johnny depp give him a few more years,what about Al pacino Not as good an actor as brando yhea right.dame judy dench only at 8,also what about dame julie walters and dame deborah karr who was oscar nominated no more than six times and ignored until she received a lifetime achievement before she died.Brian cox,brendon gleeson,,john hurt amongst others all better i think than marlon brando who only ever could mumble and do moody.the above are some of the true unsung greatest.
You should see Brando playing Marc Anthony in 'Julius Ceaser',he's not mumbling in that and he really can act although he's done some pretty awful movies like 'The Island of Dr Moreau'.
who hasnt made a bad movie but a real great should encompass all ages of cinema from the era of harold lloyd and buster keaton to the new talent of today.the problem with the actors of today is we will never see thier greatest moments to judge that will be for future generations.performances that will not date or age that,will still look as good no matter what year.that is what makes a great not being turned into a media icon of cool.
