Persistent, Niggling Questions

[Nate the Great]

PNQ: If you could see any five movies from the past on a theater screen again, what five?

This question is inspired by a fan commentary of Singin' in the Rain, where they recommend watching the movie on a big screen if possible.

The thing is, I have seen movies on a big screen that get a lot of their value from the "wow factor" I'm talking about. The Hitchhiker's Guide and Speed Racer movies come to mind immediately. I believe I also saw The Lion, the Witch, and the Wardrobe on a big screen as well.

However, in the name of more interesting answers I'll lay down a few ground rules...
1. No Star Wars.
2. Pre-2000 only.
3. Live action only.

Would I want to see Singin' in the Rain on the big screen? Of course, but does it reach the top five? I'm not sure. I think the Sound of Music could make better use of the wow factor. Going a bit more obscure, I could only imagine how good Those Magnificent Men in Their Flying Machines would look. Chitty Chitty Bang Bang, just think of it!
