Same...remember it very well, watched it at least a couple of times (last time in the nineties), maybe will watch again.
Interestingly, the move was made for just £422,816.
Translating into today's it is 18.1241X422,816=£7,663,159 or about $9.2mil-quite low, but not
crazy low price.
Cost 400K, made 8mil in box office...pretty good. Producers made 20X their money.
Avatar2 cost 2 bil (with rights, ads, etc), made $2.1-2.2 bil so far.
I think that I first saw it when I did not care about girls much, lol.
Movie was released in 1966 (US version in 1967), so unless you guys saw it much much later, I dunno...could be re-runs.
