There are two large cinemas in Rotterdam. The most well-known is Pathé Schouwburgplein, located a 5-min. walk from Central Station. The other cinema, Pathé de Kuip, is located near football stadium De Kuip.
If you go to the movie often, you could consider buying the Pathé unlimited card. You can use it at the two locations in Rotterdam, as well as in the other Pathé cinemas in The Netherlands.
