Imax Corp presented at Goldman Sachs 22nd Annual Communacopia Conference where Richard Gelfond, CEO said the following:
‘So we have two revenue streams. One is this 20% we get from the exhibitors in certain countries, it's 1.2 million, which is 50% gross margin and the second is from the studios we get 12.5% of the box office. So again just because it's on my mind it's opening next week, when Gravity opens with Warner Brothers we get 12.5% of the box office from Warner Brothers on whatever the film does in an IMAX theater and we also get roughly 20% of our joint venture theaters and then a one-time margin and a small royalty from the theaters that were opened. We're summarizing that we get roughly a third of the box office’.
Gravity is a 2013 3D film co-written, co-produced, co-edited and directed by Alfonso Cuarón. The film stars Sandra Bullock and George Clooney as surviving astronauts in a damaged space shuttle.
Cuarón wrote the screenplay with his son Jonás and attempted to develop the project at Universal Pictures. After the rights to the project were sold, the project found traction at Warner Bros. instead, and the studio approached multiple actresses before casting Bullock in the female lead role. Robert Downey, Jr. was also involved as the male lead before leaving the project and being replaced by Clooney.
Gravity opened at the 70th Venice International Film Festival in August 2013. Its North American premiere was three days later at the Telluride Film Festival. It is scheduled for wide release in the United States and Canada on October 4, 2013.
