“Edutainment funded by Lockheed Martin doesn’t sound like box-office gold, but The Dream Is Alive is the top-grossing movie in IMAX history. It has earned more than $150 million since its 1985 debut, putting it several million dollars ahead of such competitors as 1998’s Everest and 1991’s Antarctica. Yet for all its success with such films, the IMAX Corp. dislikes being thought of as a purveyor of mega-sized documentaries. It now wants to show Hollywood blockbusters on its trademark six-story screens—a strategic shift that seems to have caused the company considerable trouble.”
