Films set at MIT are less common than those that use the MIT name as metaphor. Nevertheless, MIT has been part of movie settings, in such films as "Blown Away" (1994), "Good Will Hunting" (1997), "A Beautiful Mind" (2001), "21" (2008), and "Knowing" (which also features exteriors of the Haystack Observatory). Most of the scenes for these movies, especially indoor scenes, are in fact filmed elsewhere due to MIT's reluctance to give permission to film on campus. Although portions of "Blown Away" were shot on the institute campus, the film still makes several geographical errors about MIT and Boston in general. An incidental scene in "The Friends of Eddie Coyle" (1973) was shot on location outside of MIT Baker House. A scene in "A Small Circle of Friends" (1980) was shot in Walker Memorial, an MIT cafeteria and gymnasium. The movie setting portrays Harvard University, but Harvard declined to allow the filming on their campus.
