Man, just how great is Orson Welles?

Can you name another major American filmmaker—world filmmaker, for that matter—who was not only responsible for multiple, medium-defining masterpieces but also turned in stellar performances as both leading man and supporting actor?

Cassavetes comes to mind, though he was often overshadowed onscreen by his partner and muse Gena Rowlands. Woody Allen revolutionized the serio-comic film and was, at the same time, very capable as an actor in his own screenplays; but he had a limited schtick, and one which he (and others) would eventually run to the ground. The great Silent Clowns may be close comparisons, and Welles himself professed a deep admiration for Buster Keaton. De Sica was a fine actor, certainly; and the pioneering Swedish director Victor Sjöström performed splendidly in Bergman’s Wild Strawberries as its main character.

After these (name-drop some of your own, as I’ve inevitably short-shrifted at least a few notables), though, it’s slim pickings. Clint Eastwood? A spaghetti western icon, yes, but his own films as a director do not hold a candle to Sergio Leone’s, much less Welles’s. Tarantino? Nope. Mel Gibson? Please. Tim Blake Nelson is a good actor and filmmaker—but medium-defining? No dice. (I do not count those who turned in only cameos or bit parts, such as Scorsese, Hitchcock, Sayles, etc.) And I won’t be considering up-and-comers like Greta Gerwig, Jordan Peele, or Bradley Cooper just yet, if you can find it in your heart to forgive me.
