I have this on Laserdisc, VHS, DVD (both editions) and Blueray. Needless to say, I Love This Movie.... it might figger since X is my favorite band.
oh yeah.. i also have the teaser and theatrical posters and the promo kit.
and to top it all off... i saw the movie, twice, in 1986 at the diamond point theater in waco, tx. i believe it was there for the total of 7 days.
