'Who you gonna call?' The beloved ?80s sci-fi comedy, Ghostbusters, will join the Royal Albert Hall?s Films in Concert series to celebrate the movie?s 40th anniversary. Watch Ivan Reitman?s original 1984 classic on the big screen at Halloween - all whilst Elmer Bernstein?s famous score is performed live by a full orchestra conducted by Peter Bernstein. Garnering widespread acclaim, Ghostbusters, written by Dan Aykroyd and Harold Ramis, earned nearly $300 million at the global box office and became a mega-pop culture phenomenon that endures four decades later. The film stars Aykroyd, Ramis, Bill Murray and Ernie Hudson as wisecracking parapsychologists who launch an ad-hoc ghost-catching start-up in New York City.
