Director Richard Linklater has completed shooting Before Midnight, a third film in the trilogy he planned beginning with Before Sunrise in 1995.

It continues the story of lovers Jesse and Céline after 2004's Before Sunset, reuniting actors Ethan Hawke and Julie Delpy.

"It's great to be back together again, this time in beautiful Greece to revisit the lives of Céline and Jesse nine years after Jesse was about to miss his flight," said a statement released by Linklater, Hawke and Delpy.

It was the first confirmation that a third film was under way, though Hawke had hinted at a project being written earlier this year.

Hawke, Delpy and Linklater shared an Oscar nomination for the script forBefore Sunset.

The first film, Before Sunrise, a low-budget indie work, followed a chance meeting between an American tourist and a French student on a train en route to Vienna, and the subsequent day they spend together. They are reunited several years later in Before Sunset.

Linklater also directed high school comedy Dazed and Confused and box office hit School of Rock.
