There’s a huge volume of Ghostbusters footage that has never been seen before, and a new 4K Ultra HD and Blu-ray release will finally open the containment unit.

The new steelbook re-issue of both the original film and Ghostbusters II (out June 11) features a series of behind-the-scenes treats, including this sales pitch shown only to theater owners before the release of the 1984 comedy featuring stars Bill Murray and Dan Aykroyd.

It was sent to the ShoWest convention, now known as CinemaCon, where movie theater owners gather each year to showcase upcoming titles they may want to book for their screens.

They definitely don’t soft-sell it. Aykroyd refers to it as “perhaps the greatest comedy motion picture of all time.”

Murray says theater owners should book the movie because “it’s the kind of thing where your children are gonna say, ‘Dad, I can look up to you now … And I never could before.”

The full clip is about 12 minutes long. And there’s more where that came from, including a wisely deleted sequence in which Aykroyd’s Ray Stantz visits a haunted military fort and is seduced by a ghost (seen briefly in the final movie as a dream.)

The re-release is just part of Ghostbusters building up a charge in advance of next year’s new installment in the series, directed an co-written by Jason Reitman, whose father Ivan directed the original two films.

There will be a Ghostbusters Fan Fest running at the Sony Pictures lot on June 7thand 8th, and an international Live Orchestra Tour for the original film throughout the end of the year, while Jason Reitman’s film — starring Carrie Coon, McKenna Grace, and Finn Wolfhard as a family with ties to the 1984 story — begins shooting this summer for release in 2020.
