You may already know about this, but I only recently discovered it. When I decide to go to a movie, there’s generally three cinemas that I want to choose from. On CinemaClock, there’s a way to assemble a list of movies being shown for several theatres.
Go to this page, check off the theatres you regularly attend, and then click the ‘Show selected theatres’ button at the bottom of the page. You can bookmark the resulting page and always have a customized, one stop shop for your movie-watching decisions.
UPDATE: Later in the shower, I realized that CinemaClock offers movie listings for the whole country. So, by ‘locals’ I mean ‘Canadians’.
