The US premiere of late rapper Notorious B.I.G biopic Notorious was plagued by violence.
One man is in critical condition, while three others were hospitalised after a series of stabbings at the afterparty. There was also a shooting at a separate screening.
A man was knifed several times at Brooklyn nightclub Djumbala on Saturday night. The 21-year-old remains in critical condition at New York's Brookdale Hospital. Three other men were hurt during the incident.
While the party was promoted as the "official" afterparty, Fox Searchlight insists that was not the case.
The afterparty stabbing is not the only unpleasant incident to surround the film. A North Carolina theatre has banned further showings of the film after a man was shot twice during a screening over the weekend.
The man was rushed to hospital but is thought to be in stable condition.
The film, which stars Derek Luke and Brooklyn rapper Gravy, debuted at number three at the US box office.
