Ethan Hawke and Julie Delpy wake up to possibility of Before Sunrise sequel

"Baby, you're gonna miss that plane …" The ending of Before Sunset, Richard Linklater's second instalment in the romance of Jesse (Ethan Hawke) and Celine (Julie Delpy) looked to conclude things sweetly: with Jesse failing to return to the US, and the couple reuniting properly after their nine-year separation.

But in an interview with French website Allocine, Hawke reveals that he, Delpy and Linklater are negotiating a third outing for the transatlantic couple. "All of three of us have been having similar feelings that we're ready to revisit those characters," said Hawke. "There's nine years between the first two movies and, if we made the film next summer, it would be nine years again, so we really started thinking that would be a good thing to do. We're going to try to write it this year."

Linklater, whose new film, Bernie, stars Jack Black as a mortician living in a small Texas town who befriends a mean old widow (Shirley MacLaine), also has another long-running project with Hawke on the go. The director and actor began shooting Boyhood, a fictional, big-screen counterpart to Michael Apted's 7 Up series, in 2002, and have been filming intermittently ever since. The film stars Hawke and Patricia Arquette as parents raising a child (Ellar Salmon) between the ages of 12 and 18 (which Salmon will reach in 2013).
