Oh God (1977)
This was really a damn good movie. Superficially it's a little cheesy. George Burns was the perfect choice to play God. He's funny, but with a wonderful combination of wisdom and a childlike demeanor. He was also the biggest problem with the movie. At the surface it's a bunch of pseudo-religious one-liners, like the avocado being his biggest mistake. Exactly the sort of thing George Burns was known for. It's easy to see it as simply his comedy. At the same time there's a lot more going on in the movie. Carl Rheiner correctly described it as sly, as underneath the simple jokes there's a real message, and it's kind of dark. God legitimately speaks to a man, tells him to tell others to be kind to each other, and [metaphorically this time] gets nailed to a tree because clearly he must be a loon. Jerry's doubting wife really drives the modern reality of it home with a moonshot of a line: "Of course I believe in God. I just don't think he really exists." I'm sure it's partly because I can be a tad cynical, but the grim reality of the premise really worked for me. God appears in a tortilla somewhere and it's all good and funny, but sincerely believe that he hangs out and bullshits with you while you're shaving and you'll wind up in Atascadero.
The other thing it really had going for it was John Denver and Terri Garr. Of course I'm a huge Terri Garr fan, and it's partly because she's so damned good at playing this exact roll. When you needed a typical housewife put into an impossible situation, she was the only choice. She's a natural. John Denver as the modern Jesus was an interesting choice. I found him somewhat distracting because you can't ignore the fact that he's John Denver. I kept expecting him and George to break into Saturday Nigh in Toledo Ohio. I think that's a big part of the reason why he worked, though. The point was that Jerry was the wrongest possible person for the job. Some random guy given a task he didn't want and couldn't cope with. Denver was actually a very good actor, and he really made you feel for his predicament*, and the fact that he just didn't seem to belong, being a musician rather than an actor, further added to the disconnect. He was just that much more out of place, as well as in over his head. Kind of a nervousness, I think.
*Just typing "predicament" in reference to a guy conversing with God really underscores the nature of the movie.
