Dante's Peak - Production

Production

The film was shot on location in Wallace, Idaho with a large hill next to the town digitally altered to look like a volcano. Many scenes involving townspeople, including the initial award ceremony, the pioneer days festival, and the gymnasium scene were shot using the actual citizens of Wallace as extras. Many of the disaster evacuation scenes that did not involve stunts and other dangerous moments also featured citizens of Wallace; dangerous stunts were filmed using Hollywood extras. Mount St. Helens also makes an appearance at the very end of the movie; during the start of the closing credit crawl, the scene shows an image of a destroyed Dante's Peak community with the camera shot moving out to show a wider scene of disaster, and then showing what remains of the volcano itself. The volcano that remains is actually an image of Mount St. Helens taken from news footage just after the May 18, 1980 eruption.

Exteriors were also shot at the USGS's David A. Johnston Cascades Volcano Observatory headquarters in Vancouver, Washington. The facility was named in honor of David A. Johnston, a young scientist who had precisely predicted the volatility of the May 18, 1980 eruption of Mount St. Helens, and perished during the event.

A brief scene in the movie was actually shot inside the crater of Washington State's Mount St. Helens. Specifically, it is the scene where one of the scientists gets caught in a rockslide and breaks his leg while trying to climb down to repair a malfunctioning piece of scientific equipment inside the crater of the volcano. The giveaway of this shot is a brief appearance by Mount Adams, a dormant 12,776-foot (3,894 m)-high peak 35 miles (56 km) east of Mount St. Helens, just above the crater rim as the view tightens in on the scientists.

Extensive special effects surrounding certain aspects of the film such as the lava and pyroclastic flows, were created by Digital Domain, Banned from the Ranch Entertainment and CIS Hollywood. The computer-generated imagery was mostly coordinated and supervised by Patrick McClung, Roy Arbogast, Lori J. Nelson, Richard Stutsman and Dean Miller. Despite a heavy use of CGI, the volcanic ash in the film was actually really finely shredded newspapers. Between visuals, miniatures, and animation, over 300 technicians were directly involved in the production aspects of the special effects. Due to the complexity of its visual effects, Dante's Peak was almost nominated for an Academy Award for Best Visual Effects. However, the Academy of Motion Picture Arts and Sciences chose Titanic, The Lost World: Jurassic Park and Starship Troopers instead.
