I saw this movie several years ago. it had to do with certain people interacting with each other, and there were alternate realities from past, present and future that these people existed. In the end of the movie, some guy gets killed and then wake up in I guess what was the "true" reality (which was futuristic) and he took off a headset that I guess was how his mind was connected to the previous reality he was just killed in, and he walks out to see people he thought were dead standing out by a river or something.
Very sorry if this is confusing, but I'm trying to figure out what some movies are that I've had spontaneous memories of over the last month or so... I wanna get them in time for XMas.

Here's the list of movies I wanna get so far:

eXistenZ
Gattaca
A Beautiful Mind
The Mighty
Gladiator
Pearl Harbor

I got 7 movies a few days ago:

Cellular
Con Air
Heat
Dante's Peak
The Core
Enemy of the State
12 Monkeys

Anyway, if anyone can help me figure out the movie I'm stumped on right now, I owe you access to my FTP for some wicked software, or an E-card or something, lol.

Nevermind, my friend helped me figure out that it was this movie:

The Thirteenth Floor (1999)

Darn it.... I wanted to contribute something trivial and questionable in it's community usefullness..

Anyway my 1st (and only guess) was 13th Floor (before I even scrolled down).

I only knew it since a friend of mine is kinda into that movie big time and I just saw it (again) recently.

That was a weird but interesting movie.

Sounds like a really interesting movie. I might have to go and see if I can't rent or buy it.

I rented both The Thirteenth Floor and Gattaca. They seemed like good movies.
The next two movies I want are He Got Game and A Beautiful Mind.
