WHEN the Museum of Modern Art shut down its Manhattan campus for major renovations and moved its exhibits to Long Island City, Queens, MoMA’s popular film program was left homeless.

Now comes word that, starting in October, MoMA will be showing flicks at the Gramercy theater on East 23rd Street.

The program will kick off with a festival of restored films, including two by Kenji Mizoguchi, four by Ernst Lubitsch and the original German version of Max Ophuls’ “Lola Montes” (1955).

A retrospective tribute to French actress Delphine Seyrig will follow.

The 499-seat Gramercy opened as a moviehouse in 1936. In 1998 it was converted into an off-Broadway theater.
