Cool info about Xavier's chair:
Also, here's a fun little tidbit, Xavier's wheelchair is the same one Patrick Stewart used in Singer's original X-Men film: "It’s the original chair from the first movie – we bought it from a collector.

My memory is hazy about the chair, but I thought I remembered it being bought by a lawyer in one of those eBay prop auctions in August 2000. I also thought I remembered he wouldn't let be purchased back for X2 and 3, so the crew had to build another version. The story was told on one of those featurettes or commentaries from the X2 DVD, but I'm too lazy to find it and verify. Whatever the true story, it's cool to see it back and a nice piece of trivia.
