Ah, now I see it. ;) apparently it was rated X in UK originally, so it's probably a lobby card made for UK cinemas, yeah it's weird but we're talking about the country who put Sam Raimi in court for The Evil Dead in the eighties so it's not that hard to believe, 15 is the UK video rating, erri_wan.

ChainsawAsh-- the lobby card we're talking about is linked in his post.

This is interesting.

According to the BBFC, a 95-minute cut was rated X in 1971.

In 1988, an 82-minute cut (home video, so about 86 minutes without PAL speedup) was rated 15. Another 82-minute home video cut was rated 15 in 1992. This is the "original" (laserdisc) cut.

In 2004, an 84-minute cut (also home video, so about 88 minutes minus PAL speedup) was rated 12. This is the 2004 Director's Cut.

But the 1971 theatrical cut was 81 minutes. What the hell is this 95-minute, X-rated version released in the UK in 1971? Could that have included trailers or something?
