At the end of their bus ride through bombed-out Frankfurt, the main characters arrive at the massive I.G. Farben building. Completed in 1930, it was once the largest office building in Europe and home to the giant chemical business. From 1945 to 1952 it was the location of SHAEF (Supreme Headquarters, Allied European Forces). From 1952 to 1994 it was the headquarters of the U.S. Army's V Corps. In 1996 the building was acquired by the state of Hesse, and after a $25M renovation became the Westend Campus of the University of Frankfurt. The small, continuous elevators seen in the film, called paternoster lifts, are still in use.
