"Playing God" is also the answer to the question "What do George Burns and Alanis Morissette have in common?": Burns portrayed the deity in a series of three films starting with Oh, God!, and Morissette took on the divine role in Dogma.
Actually, playing God is what quite a lot of actors have in common, as I discovered when I decided to delve into what the Internet Movie Database (IMDb; http://www.imdb.com/) had to say on the subject. Below are the results of my investigations: a list of actors who have played God (or supplied the Voice of God) on film, and the names and dates of the films in which they did so. From the raw IMDb results I have weeded out red herrings (characters whose names or descriptions have the string god in them but who do not appear to be "the" God) and also the video and television results, and I have grouped male and female actors together into a single chronological list. I've also noted cases in which the actor playing God also has one or more other roles in the same film, such as major prophets, the devil, or Bugs Bunny.
Because this list is based on a secondary source, I cannot vouch for its completeness, and since it contains a great many films I have not seen, I cannot be sure that all of the roles included really are "God" in the sense of "the deity" (as opposed to, say, "God" in the sense of "some guy named Godfrey who's called 'God' for short"). Still, I hope that my list will prove both amusing and informative as a picture of how cinematic protrayals of God have changed—or not—over the last six decades or so.
