A while back I posted my desert island collection which also included television at Flickering Myth.

As for the ones listed by Roger Ebert, I admire Citizen Kane for being cutting edge at the time but the one I absolutely love after all these years is The Third Man; it has it all: intrigue, romance, and humour not to mention the film is visually stunning.
