I'm from Ireland and "blue movies" used to be a common term for pornographic films and I'm fairly certain that our British neighbours also used this terminology. However, while typing this comment it occurs to me that I haven't heard the term in many years and I suspect it has fallen out of fashion as Internet sites have taken over from sex shops (which really only arrived in Ireland in the mid to late 90s).
