"The Interview," the Sony Pictures film about a fictional plot to assassinate North Korean leader Kim Jong Un, opened in more than 300 cinemas across the United States on Christmas Day, drawing sell-out audiences in many theaters where outspoken patrons said they were championing freedom of expression.

Seth Rogen, who co-stars in the low-budget comedy with James Franco, and co-director Evan Goldberg surprised moviegoers by appearing at the sold-out 12:30 a.m. PT screening of the movie at a theater in Los Angeles where they briefly thanked fans for their support.

Sony Pictures this week backtracked from its original decision to cancel the release of the $44 million film after it became the target last month of the most destructive cyberattack ever on a U.S. company.
