 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 films overall domestic total.
