British film couple Kate Winslet and Sam Mendes have finally decided on a movie project, years after declaring they would love to work together.

The Titanic beauty, 30, and her director husband, 40, married in 2003 and they have always expressed their desire to collaborate, as long as the timing is right.

Winslet said, "It just has to be the right film, in the right country and at the right time because of the children and school."

British newspaper the Daily Mail reports the couple have fallen for RICHARD YATES' 1961 novel REVOLUTIONARY ROAD, about a bored couple in suburban Connecticut in the 1950s.
