What was the first R rated film you saw at the cinema?

[OhWhatFuckeryIsThisNow]

We are watching On Flew Over the Cuckoo's Nest with dd 19. I remember seeing it with my mates at the new cinema in town. I felt ever so grown up and quite shocked at the language. (I'd never heard a grown up say "cunt" before) God it was good.
For those of a certain age, what was your first time?

Goodfellas - it was an 18 when it came out (I wasn't 18 ) I went to the cinema with a boy I had the most godawful crush on . We spent the whole film kissing, it was absolutely fantastic. 27 years later it's still "our film".

Terminator 2. Remember loving the violent bits, which was odd as I'd been v/sensitive to violence up until then, and the effects still holding up incredibly well - I didn't see it on release. Still remains an all-time favourite and I can't wait to see it on the big screen next month.

As an aside, it's interesting how standards for what constitute 'adult' material change over time. I saw One Flew Over The Cuckoo's Nest at a recent BFI screening and the rating had been dropped from 18 to 15. Sensible decision as there can't be many 15 y/o's who haven't heard "cunt" and the violence, although bloody, is brief.
implantsandaDyson Goodfellas is still an 18 though (solely for violence these days) which I agree with.

^ silly me for not reading the title. T2 was my first R on DVD - can't remember what it was at the cinema unfortunately.
