To try it out, fire up google.com on your iPhone, webOS or Android device, search for "movies", and click on the "More movies" link. If you're not getting any results, it may be because the service is only available in US, UK, Canada, Ireland, Australia, and New Zealand.
You can also browse by theater, which will take you to a map displaying the theaters near your current location. Tapping any theater on the map will display a list of shows now playing. Finally, you can search for a movie or a theater directly.
