Milos Forman's "One Flew Over the Cuckoo's Nest" closes tonight in Stockholm after a record run of 573 straight weeks, the distributor said Wednesday. The movie, starring Jack Nicholson as a defiant patient at a mental institution, premiered in the Swedish capital on Feb. 26, 1976. The movie opened at the downtown Cinema Theater and moved to various houses during the 11 years but never missed a day. It is back at the Cinema Theater for its closing. About 2 million people, about one-fourth of Sweden's population, have seen the movie, said Inger Johansson, information chief of the Sandrews distribution company.
