===Omnitheater===
The Mississippi riverfront facility has a convertible dome [[IMAX]] theater. With both a wall screen for IMAX films and other flat-screen presentations and a rotating [[dome]] for viewing IMAX dome presentations, it was the first convertible theater in the northern hemisphere. The [[counterweight]]s for the system were so massive that they had to be put in place before the rest of the building. When it opened in 1999, the theater boasted "the largest permanently installed electronic cinema projector in the world", an advanced computer system to coordinate the theater's facilities, and a complex sound system to accommodate both viewing formats.

In summer 2019, the Omnitheater briefly closed to convert to digital laser technology. In October 2019, it reopened as the world's third-largest digital laser IMAX dome theater.

The museum is a leading producer of giant screen films, including:
*''Genesis'' (1978)
*''Living Planet'' (1979)
*''The Great Barrier Reef'' (1981)
*''Darwin on the Galapagos'' (1983)
*''Seasons'' (1987)
*''[[Ring of Fire (1991 documentary film)|Ring of Fire]]'' (1991)
*''Tropical Rainforest'' (1992)
*''Search for the Great Sharks'' (1995)
*''The Greatest Places'' (1998)
*''[[Jane Goodall]]'s Wild Chimpanzees'' (2002)
*''Tornado Alley'' (2012)
*''National Parks Adventure'' (2016)
*''Ancient Caves'' (2019)

The theater was briefly closed in early 2014 to repair a leaky roof.<ref>{{cite web|url=http://www.twincities.com/localnews/ci_25219382/science-museum-repairs-leaky-omnitheater-roof|title=Science Museum repairs leaky Omnitheater roof|date=23 February 2014|publisher=[[St. Paul Pioneer Press]]|access-date=2 January 2018}}</ref>
