The Ivan Reitman directed films “Ghostbusters” (1984) and “Ghostbusters II” (1989) are both getting a special 35th Anniversary Limited Edition 4K UHD Blu-ray Steelbook release on June 11th via Sony. The “Ghostbusters 1 & 2: 35th Anniversary“ Limited Edition 4K Steelbook had first been reported by the folks over at Ghostbusters.net and now it is available for pre-order over at Amazon. The 4K tech specs remain identical to the previously released 4K UHD Blu-ray versions of the two films. However, a large number of new bonus materials are going to be included exclusively in this release. The full list of extras set to be included on an extra bonus disc can be found below, after the break.
