Venerable repertory film theater Film Forum has been operating in New York since 1970. That’s no small feat when you consider the various challenges such an institution faces, including new technologies—from VHS to streaming—that compete for cinephiles’ attention and the commercial real estate market in New York, where the life of a business is largely determined by the length of its lease. As an example of the latter, two movie theaters closed last month in Manhattan because the landlords did not renew their leases: the Landmark Sunshine will be demolished and converted to office space, and the Lincoln Plaza Cinemas will undergo some kind of structural renovation to the building—and may again house a movie theater.

Film Forum’s Director of Publicity, Adam Walker, gave a presentation in Utah at Art House Convergence, a gathering of film distributors and exhibitors, about the history of Film Forum. Film Forum posted the presentation on their website The presentation describes several milestones: the various moves that Film Forum undertook that culminated in their current home on West Houston Street, their expansion from one screen to two screen and ultimately to three screens, and the addition of personnel that has shaped their history. The presentation also explains why you often have to sit behind a column when watching a movie there and the origins of their distinct printed calendars.

If you prefer experiencing the presentation in a slideshow format, you can also see it as a slideshow on Indiewire’s website.

Spoiler alert: There was one happy note at the end of the presentation that I am happy to relay. Film Forum recently extended their lease to 2035. This means they’ll likely be around for another generation. And because of this newfound security, they have begun renovating their current space and plan to open a fourth screen.
