Rocky Mountain Express premieres in Montreal

The first IMAX film featuring a Canadian subject, Rocky Mountain Express,  will be screened tonight at the Scotiaban Theatre in Montreal.  It's a fundraising event for the Canadian Railway Museum in St. Constant.
The IMAX format was invented in part by Canadian Colin Low whose son Stephen directed the film.  Sonali Karnick spoke with the film's producer, Alex Low who happens to be Stephen's brother.
