Imax Corp. IMAX, +6.33% said Monday it has enjoyed its best ever October with global box office at $100 million and counting, beating the previous record takings of $84 million in October of 2013. The operator of cinemas with 3-D and other enhanced screens said the record was mostly due to the strong performance of "Dune," the science-fiction blockbuster directed by Denis Villeneuve, which chalked up $9 million in North American Imax theaters to account for 22.5% of the film's overall domestic total. "Filmed with IMAX cameras, Warner Bros./Legendary's "Dune" scored IMAX's biggest global October opening weekend ever -- earning $17.8 million globally across the IMAX network for the weekend, an unprecedented 20% of the film's weekend total," the company said in a statement. "Dune" debuted on 1,300 Imax screens in 36 countries and captured 23% of overall box office in China, 19% in the UK, 18% in South Korea and 30% in two weeks in Japan. Imax shares were slightly lower premarket, but have gained 21% in the year to date, while the S&P 500 SPX, -0.11% has gained 21%.
