the theme music in which a masculine chant of the melody was added, as well as a shot of a forest with a feminine sigh added to the score as the expanse is revealed. To mark the film's 35th anniversary, screenings were charged at 50 cents for adults and 25 cents for children, the same price used until the 1980s; during its opening, it was charged at $1 for adults and 50 cents for children. The Airbus IMAX Theater of the Steven F. Udvar-Hazy Center has screened the film it since its opening. Other theaters To Fly! spurred the construction of new IMAX theaters in the US and internationally; there were previously just five in the US. The Smithsonian later also built an IMAX theater, named after Samuel C. Johnson, at the NMNH. Museums "went crazy" over the film, specifically the transformative opening sequence.
