Flixster now has showtimes for pretty much every theater in the US, UK, and Canada. (We get our data from the same place as yahoo/google so its as real as it gets.)
Our thought was that it would be cool if you could see what your friends said about a movie right in the same place you were looking up what to see - hopefully people won't need to come to flixster first and then go somewhere else anymore.
Oh, and you can even buy tickets online for some theaters if you're into that sort of thing.
made some improvements to this tonight - now showing theaters ordered by how close they are to you and also giving the option to view more theaters if there aren't enough in a 5 mile radius.
