Four men were stabbed early yesterday, one seriously, during a Brooklyn party for the release of a film about rapper The Notorious B.I.G., officials said. Police responded to a 911 call at 3:25 a.m. about a stabbing in the Djumbala nightclub at 1370 Ralph Ave. in East Flatbush.

One victim, 21, had been stabbed several times, and the other three had each been stabbed once, police said. All were taken to The Brookdale University Hospital and Medical Center, where the 21-year-old was listed in critical condition and the others were in stable condition, police said. A representative of Fox Searchlight, which is distributing the film "Notorious," said the party had no connection to the film.
