After bonding over a revival of ``Cabaret,'' Alan Cumming and Jennifer Jason Leigh will next join forces on an unusual film collaboration at Fine Line, where they will co-direct ``The Anniversary Party,'' based on a script they wrote together. The duo will play the starring roles.

``Jennifer made a film and told me how quick it was to work on digital video, so we made up a story, pitched it and then wrote a screenplay,'' Cumming said. ``It just grew into a monster.''

They play an estranged couple who reunite and hold a sixth anniversary party to commemorate the event. The tensions involving friendships and professional relationships at the party threaten to pry the couple apart once more.

Cumming, who just wrapped ``Spy Kids'' with Antonio Banderas, gets behind the camera after completing the Alan Rudolph-directed ``Investigating Sex'' with Nick Nolte and Neve Campbell. He's also booked for ``Josie and the Pussycats'' at Universal after doing ``The Flintstones in Viva Rock Vegas''

Cumming, who did a small screen turn in ABC's ``Annie,'' has also signed to co-exec produce with Alan Heinberg (''Sex and the City'' and ``Party of Five'') and star in a documentary-style series for HBO about celebrity in America. He also returns to Broadway in January alongside Julianne Moore in ``Design for Living.''
