Rocky Mountain Express propels audiences on a steam train journey through the breathtaking vistas of the Canadian Rockies and relates the epic adventure of building the nation’s first transcontinental railway.
The completion of the Canadian Pacific Railway (CPR) in 1885 ranks among the greatest engineering feats in history. The project drew on the labour and expertise of thousands from around the world, including a young American railway superintendent named William Cornelius Van Horne. If the builders had failed, would Canada exist today? Spanning thousands of miles and some of the world’s greatest natural barriers, this grand transcontinental project and its wandering ribbon of steel drew together far flung communities isolated in the wilderness, shaped a new nation and changed the face of the North American continent forever. The success or failure of the venture was decided deep in the mountains.
Retracing the original route aboard the majestic steam engine 2816, the audience is transported back to the age of steam to re-live this alpine nation-building odyssey. The film weaves together spectacular IMAX aerial cinematography, breathtaking vistas of the west, archival photographs and maps and the potent energy and rhythms of a live steam locomotive to immerse audiences in a an era of remarkable ingenuity and struggle and a region of stunning natural beauty. Ride the rails along deep river canyons and over high mountain passes. Discover some of the most beautiful and rugged landscapes on earth and the heroic human drama and epic engineering that shaped a continent.
National Geographic's LEWIS AND CLARK - GREAT JOURNEY WEST takes a step back into history. It was the dawn of a nation—a time before the American West became known as the frontier, and little was known about what lay within. Two captains, courageous in spirit and unyielding in their dedication to their mission, led 31 people, including one woman and her infant son, to the Pacific Ocean and back. Now, 200 years after the launch of the expedition, this breathtaking drama is captured for audiences in the newest large-format release from National Geographic. Audiences will experience the danger and beauty of the unknown West as it unfolded before the eyes of Lewis and Clark .

What makes the difference between the Riverfront Park IMAX Theatre image vs. other area theatres? The 70 millimeter IMAX film used in our films are 10 times larger than the standard film used in standard theatres. Each film frame is 3 inches by 2 3/4 inches. Each frame is pulled through the projector at 24 frames per second thus providing a much higher quality image presentation. These images are then projected onto the screen via a 4,500 watt Zenon lamp. There is conjecture that if this lamp were turned on uncovered outside of the IMAX theatre, it would be bright enough to be seen in space. The final images are presented onto a screen which is over 53 feet tall by 69 feet wide.

IMAX film does not include an embedded soundtrack as do other film theatres. A separate digital 6-track recording is synchronized to the film frames. These audio tracks are played directly off a hard 
disk drive which is then distributed directly to the amplifiers rather than using a decoding method, such as Dolby Digital. The audio is then presented via our six speaker system producing a three dimensional effect. This method of production accounts for our higher quality sound experience.
The Riverfront Park IMAX theatre also has assisted listening devices available for persons with hearing impairments. Our wireless system offers both standard wireless receivers with Ear Speakers and “T” coil neck loops for patrons with applicable hearing aids. Please consult our staff at the concessions counter for assisted listening devices.

The original IMAX Theatre at Riverfront Park was built for the World’s Fair - Expo 74 and was located under the U.S. Pavilion tent structure. The system was only the 3rd IMAX film system in existence at the time. The present IMAX facility was designed and constructed in its current location in 1978. The Riverfront Park IMAX theatre was designed exclusively to accommodate the IMAX experience. The increase resolution of the film has allowed the audience to be much closer to the screen and the theatre seating is placed at a much higher angle than typical conventional theatres. This design allows viewers to experience the show throughout their entire field of vision and feel as if they are inside of the movie.Incidentally, the term IMAX stands for Image MAXimum.
