I was also going to mention to be prepared for being scared of the dark room with the very loud noise. My DS has just seen his first movie and now second aged 4.5yrs. The two times before that he ran screaming when we tried. We tried toy story and yogi bear....small town & small cinema and he still couldn't handle it. So we just left it til he was ready & went with other friends to ease him into it.

Each child is different though. Also my DS1 will not sit still to watch a movie at home so was fair chance at that age he wouldn't watch an entire movie. Does he watch movies at home?? we didn't introduce DS1 til movies even at home until after age 3 as he just didn't sit long enough.

all you can do is try I guess.
