Chris Marstall, the founder of Tourfilter, decided he wasn't satisfied with helping people track their favorite bands. He realized something was missing when it came to local movie schedules.

As Boston movie connoisseurs are aware, Greater Boston is always on top of the film scene. The Brattle Theatre, Coolidge Corner Theatre, the Harvard Film Archive, and the Museum of Fine Arts could keep you in a theatre seat every single night with current arthouse hits, retrospectives, and foreign films that somehow fell through the cracks.

Unfortunately, information about these theaters' schedules isn't always easy to find. Sometimes the theaters post trailers for the movies, and sometimes they don't. Sometimes you have to dig in a few layers to get more information about a movie. Sometimes you can't track sudden programming changes unless you check a site every few days. And that's where Antiplex comes in.

Antiplex combs the websites for the Brattle, the Coolidge, the HFA, and the MFA and lists what's playing each day in reverse chronological order. The site also crawls for summaries and photos, so if you thought you wanted to see Code Unknown (which is playing at the HFA on Sunday, October 28, at 9:00 pm, by the way) a long time ago but forgot what it was about, all the info is right there for you.

The site also pulls in a corresponding YouTube trailer, if one is available. Since Antiplex is a work in progress, you might encounter a bug or two, but Marstall is at work fixing the bugs. You can also pitch in to repair problems, such as when YouTube trailers don't match up to the movies. In that case, you can click a button that lets you search YouTube for the right trailer or upload a trailer if you happen to have one on hand.

Marstall already has thoughts on Antiplex's future. In an e-mail, he said he is thinking about enabling users to post announcements for one-time venues, to rate the movies, and to comment about them. He would also like to "reach out to different area film festivals, see if there is a way to heighten their profile, [and] make it easier to find out about the movies they're showing."
