Phil Grabsky’s fine new documentary In Search of Mozart has broken the Gene Siskel Film Center’s box office record for the most successful single-week run. Marty Rubin, the center’s associate director of programming, reports that only  Bonhoeffer, Martin Doblmeier’s documentary about the German theologian, and Edmond, Stuart Gordon’s star-heavy adaptation of the David Mamet chestnut, have grossed more—in runs of five and two weeks respectively. 

Film Center management knew something was up on Friday, April 13, the first night of the engagement, when the movie had to be moved from the smaller 61-seat theater to the main 197-seat theater. Since then nearly every show has been a sellout; the movie’s numbers are even more impressive given that the Film Center was closed on Wednesday, April 18, for a private rental.

Rubin attributes the movie’s success to heavy promotion on classical-music station WFMT, including three on-air interviews with programming director Barbara Scharres, and says the Film Center has scheduled a return engagement for June 1 through 7.
