Eugene O’Neill is said to haunt the fourth floor of Kilachand Hall (formerly Shelton Hall), but that’s not what drew the team behind the new Ghostbusters reboot to BU. It was the gothic architecture of the BU Castle, which appears in the film as the Aldridge Mansion Museum, that captured the attention of the film’s location scout.

Scheduled for a July 2016 release, the new female-driven horror-comedy is directed by Paul Feig (Freaks and Geeks, Bridesmaids) and stars Kristen Wiig and Melissa McCarthy. Filming began in Boston in June under the code name Flapjack and in mid-August the Castle got its star turn. The original Ghostbusters, starring Bill Murray, Dan Aykroyd, and Sigourney Weaver, was released in 1984.

Nicolle Paeglow, the Castle’s associate director of finance and administration, says the historic Tudor mansion is on Hollywood’s radar after appearing in scenes in films like 21 and The Company Men. She says the pro­duction team originally hoped to use both the inside and the outside of the building, but scheduling constraints limited them to a one-day exterior shot, which was wisely done when classes were not in session.

Look closely at the sign put up by the film crew and you’ll spot a typo: a missing apostrophe and letter “s” in the phrase “New York’s oldest.” We won’t hold it against them.
