Apart from when I was a child, I don't think I have seen a 3-D movie.
I sometimes get a note flashed across the tv screen that "this programme is available in 3-D" however I always assume it is a mistake as they are just ordinary programmes that are often on weekly, and I doubt they would be available on 3-D - next time I will get the glasses out and press the 3-D button however....all my TV's came with about 2 sets of glasses though no idea where I put them.
I think I took the kids to one when they were little. I was doing a clean up last year and found a whole lot of glasses. I have a feeling that there was a special screening of Titanic in 3D that my husband and I saw, at least I think it was Titanic.
I saw a wildlife 3D movie at The Imax, Darling Harbour, then a VERY short 3D film at The Australian National Maritime Museum, in Sydney. These 2 were in the last 5/6 years.
I have seen 3d movies. I don't like them much as they make me feel a bit sick. I've never watched 3d television and I don't think you can on the TV that we have.
