Facebook is launching two new ad units designed to help movie studios promote their latest releases.

The first unit is called a movie reminder ad, and it does exactly that —since studios usually start marketing their titles months or even years before release, they can now include an Interested button in their Facebook ads, allowing users to opt-in to a notification when the film is released.  Then, on the Friday before opening weekend, interested moviegoers will get a reminder pointing them to a page with showtimes and ticket purchase options from Fandango and Atom Tickets.
