One actor/actress to rule them all

[Mirage]

i don't want any actors or actresses in positions of power. we tried it once with reagan and just look how well that went

[Loony BoB]

Just recently I've been picking up on some films by Phillip Seymour Hoffman that I'd missed while binging on 70's, 80's and 90's trash. With him, you get:

Charlie Wilson's War
Capote
The Master
Moneyball
Synedoche, New York
Punch Drunk Love
Almost Famous
State and Main
The Big Lebowski
Magnolia
Boogie Nights
Hard Eight

Which is not bad, but I'll still be an action fanboy and say I'd pick Arnie.

It's amazing how many great movies he's been in. Your list doesn't even note Scent of a Woman, The Talented Mr. Ripley, Cold Mountain, Red Dragon, Mary and Max, The Boat that Rocked, The Invention of Lying, Mission: Impossible III, The Hunger Games films... the list goes on. He's actually a contender for my choice now. Geez.

Morgan Freeman has been in a lot of films I like. Him probably, or Tom Hanks.

Tom Hanks is another good shout, be it his 80's comedy then moved into his more seriously stuff. I like both so I'd be sorted.

For actor, I'd pick Grouch Marx.
