Hit the jump for details on all the aforementioned new Blu-ray releases.

My Blu-ray budget is about to expand significantly as we inch closer towards the holiday season, and the Steven Spielberg trifecta kicks off this month with the Jaws Blu-ray, followed by E.T The Extra-Terrestrial and Indiana Jones: The Complete Collection in the ensuing weeks.  A full list of the special features included on the four-film Indiana Jones Blu-ray set has now been released, and it appears that only one new documentary will be on the set.

Nevertheless, the two-part “On Set with Raiders of the Lost Ark” boasts nearly an hour of rarely seen footage from the set and archival interviews, and the collection also includes a 1981 making-of documentary for Raiders that was previously unavailable on DVD as well as all the bonus features that appeared on earlier home video releases of all four Indiana Jones films.  Hit the jump to check out the entire list of what the set entails, including specifications.  Indiana Jones: The Complete Collection hits stores on September 18th.

It’s gonna be one hell of a Blu-ray season this fall for Steven Spielberg fans.  Jaws comes to Blu-ray for the first time on August 14th, E.T. The Extra-Terrestrial hits the format in October, and now a release date has been set for Indiana Jones: The Complete Collection.  We previously learned that Indy would be getting the HD treatment back in February, but now Lucasfilm and Paramount Home Entertainment have announced that the set will hit stores on September 18th.  The collection includes remastered versions of Indiana Jones and the Temple of Doom, Indiana Jones and the Last Crusade, and Indiana Jones and the Kingdom of the Crystal Skull, as well as a completely restored version of Raiders of the Lost Ark supervised by Spielberg and sound designer Ben Burtt.

The discs will include documentaries, interviews, featurettes and “new bonus features,” though it hasn’t yet been announced what these new features entail.  I’m pulling for an extended, candid retrospective with Spielberg, George Lucas and Harrison Ford, but that seems unlikely.  Hit the jump to check out the artwork, read the press release, and watch the previously released Blu-ray trailer.
