The trilogy of "Back to the Future" (Back to the Future) has as of today its deluxe edition on Blu-ray 4k, a true collector's item for fans of this story created by Robert Zemeckis between 1985 Y 1990.

Starring Michael J. Fox y Christopher Lloyd, the return occurs 35 years after the launch of one of those films that forever changed the history of cinema and that to this day are still one of the most loved by lovers of the Seventh Art.

However, How is this edition composed? As it is an anniversary edition and the "Back to the Future Day" (then we will explain why), this realization comes in two different versions.

First comes the Blu-ray edition of the trilogy, that is to say, not in its 4k version (1080p definition instead of 4K ultra high definition). Each of the discs is fully remastered in terms of image and sound and also includes bonus material.

In the second case, the desired discs arrive in 4K, that to give it a more special touch is separated in metallic boxes, united, form the photograph of the endearing DeLorean, the most famous time machine. Then, we show a fragment of 10 minutes shared by Universal, where you can see the quality of 4K (you need to change the settings).

Each film is remastered with HDR10 + effects and multi-dimensional sound and bonus material is also included. But another of the great gifts (in a limited edition), is the replica of “Hoverboard” appearing in the second and third parts of the trilogy.

Additional material (that is included in the two editions) brings about an hour of never-before-seen content, as a tour of the Hollywood Museum by co-writer and producer Bob Gale, with accessories and anecdotes from the filming.

On the other hand, "Back to the future: the musical behind the scenes ", which includes the recording of two new songs and a roundtrip of questions and answers with the filmmakers and the original casting.

"An alternative future: the lost auditions ”is the option that shows the film that could have been made with a record of unpublished auditions carried out by the now famous actors.

There will also be space to explain the phenomena of physical laws that have actually been violated to tell the story and that are now explained by Dr. Michio Kaku in a special edition.

Finally, the footage is completed with deleted scenes, a documentary, music and promotional videos, shorts, the design of the DeLorean and a meeting with Michael Fox.

Because a 21 October?

However, because a 21 October is this launch? Not everything is coincidence, since today is celebrated the "Day of Back to the Future", following that in the second part of the trilogy, el Doctor Brown (Lloyd) y Marty McFly (Fox) they travel to that same date, but of the year 2015.

To that future (that is already part of our past) the protagonists must go in order to save Marty's son from being imprisoned.

In that remembered scene, the characters will find endless technological advances and also Marty will find the sports almanac that will serve as a trigger for the rest of the story.
