I saw this animated short in film history class at Michigan State in about 1966. A writer is tormented by a giant letter A. After battling it in various ingenious ways for 10 minutes, he defeats it. Then a giant B appears. Cute.
The Internet Movie Database lists movies with the titles A, B, D, E, F, G, H, I, J, K, L, M, O, P, Q, S, U, V, W, X, Y, and Z. There is also a film titled Pi, which I haven’t seen. I’ve only seen A, M, and Z. The movie O is available on video; I think I’ll check it out. None of the others are available, or if they are, they’d be terribly hard to find. Oddly, there are no movies entitled C, N, R, or T. Something should be done about that. Somebody alert the Directors Guild.
