Where To Buy This Movie...
If you live in the U.S., you'll need to have a DVD player that allows you to change regions, and also covert PAL to NTSC.
If you want to be able to play ANY DVD from ANY country, regardless if their video frequency is different or the DVD region code for their DVD's is different than your country, then you can buy a very inexpensive but very nice DVD/CD/MP3 player that lets you change regions, and flawlessly converts PAL video to NTSC video. Many players will convert PAL to NTSC, but many also distort the aspect ratio of the video while converting it. This player does it perfectly, and it costs much less than the DVD player you probably already have I'll bet. Here's a link to it on Amazon.com (U.S.):

Read the reviews for this thing. I love mine!!! I actually bought two of them, just so I have a back-up one in case they stop selling them.
It actually lets you disable the Macrovision copy protection as well, if you know the proper remote control keypress sequence (search for it via Google).
You can purchase a PAL Region 2 copy of this DVD from Amazon's UK store.
