The Radiance and Soverign class ships are the only ships with regular movie theaters but the Radiance class is much nicer. They are not shown in the main theater showroom like some people think. They built an actual small theatre, just outside the sports bar with stadium seating, and it holds about 50 people. When I was last there they usually had 2 or 3 showings a day, at 2pm, 5pm and 8pm roughly.
