For the moment let's talk about film, because for what I'm about to ask only film, not stage, makes any sense.
Orson Welles was Falstaff, Macbeth, Othello, Lear, Shylock.
Sir Laurence Olivier was Orlando, Henry V, Hamlet, Lear, Richard III, Othello, Shylock.
How about Richard Burton? Not only was he Hamlet and Petruchio, he was Caliban as well.
...so, here's my question. What actor (or actress), who is no longer with us, makes you wish "If only he'd played ________" and now we'll never know.
See what I'm getting at? This is why I said film. Because even though Olivier and Gielgud were decades before my time, I can at least go to film and get a glimpse of what they were capable of. But if Olivier never put a Macbeth on film, well then I'll never get to see Olivier's Macbeth. Dig?
Who do you wish we had?
