Movies available on TV in cabins. You have to pay for some of them I think. There are other free programmes depending upon which reception area the ship is in. We were told there was a small, rather useless film room on the lowest deck which was always full on sea days & difficult for those at the back to see the screen. We set off one day to find it but never came across the place so my info is second hand. However, there were lots of other things going on, day and night so you might not miss the big screen too much. Enjoy. We did.
There is movies on TV in all Cabins if you need to pay for it that depends on what cabin grade you have higer cabin grade not need to pay lower cabin grade you need to pay. Everyday you get the Cruise Compass who is the daily "newspaper" and there its say what movies you can see and what time in the Cinema. And the cinema is named scoreboard. But you will have so much other choices onboard that you will not get borde.
