There was a nine-year gap between 1995's "Before Sunrise" and its 2004 follow-up "Before Sunset". The same length of time looks set to happen for a third film in the series which is aiming to be in cinemas next year.
Still untitled at present, Ethan Hawke confirmed to Indiewire recently that "we're doing a follow-up to Before Sunrise and Before Sunset, so that will be fun. We’re going to shoot that this summer."
Last November Hawke said "All three of us have been having similar feelings that we're ready to revisit those characters." Looks like they're following through on the promise.
The big question of course is what will the title be? "Before Moonrise," "Before Midnight"?
