Very rarely, most of the films I watch are in English. I think I watched 10,000BC or something like that in the cinema with subtitles once, but I find I end up reading the subtitles constantly and missing what's going on in the picture.
I have watched a couple with them yes, but its hard to follow them and watch the film at times, have to really concentrate. The last film i watched was a film called ''22 Bullets'' starring Jean Reno who did ''Leon'' thought that was a brilliant film..
I always tend to watch movies and shows with subtitles. I find that one of my ears have worse hearing than the other which doesn't help but I also can find it quite hard to understand regional accents and such so having subtitles on allows me to actually watch the film I find! Certainly better than what I used to do which was listen and hope I heard it right so that I could understand what was happening, haha.
