How to....duplicate screens on two laptops.....?

Hey everyone...
I am leaving on a trip in 3 days that I was hoping I could do this on...so I need information quick please.

Me and another guy are taking laptops on this trip. We are going with a bunch of friends, and we are taking a bunch of movies. The problem is...is that in a plane, and even in normal situations, we can't exactly get a whole bunch of people around one laptop screen (at least not comfortably). So what we were hoping we could do is......
network the two computers, and then somehow, run the dvd off of one of the laptops, and have the movie show up on both laptop displays.....if possible.
We are not sure at all if this is possible, but any feedback would definetely be helpful, if not a different solution to the problem.

Thanx!
