Director Paul Feig once said that his original cut for this year’s Ghostbusters was four and a half hours long, which he then cut down to a “slim three and a half hours.” In the end, the movie was 114 minutes, but the extended cut (available on DVD and Blu-ray on October 11th, available in digital form now) has added 15 minutes of extra moments. Is it worth it? That depends on how much dancing you like.
