Most retailers are charging more than this for the standard case and it's a true 4K movie not an upscale from 2K like a lot of recent movies.
Brian Henson, via a leaflet included with the release, writes this about the new picture presentation for Labyrinth:
Using the original 35mm camera negative as the source, the film was scanned and fully restored at 4K resolution.This resulted in a significant increase in detail, color and vibrancy -- key elements to the film's unique and sophisticated visuals, from the layers in Jareth's costume as he starts Sarah on her adventure to the intricate features of the goblins that inhabit the labyrinth itself. It has been exciting to bring the look of the film back to how it was originally intended -- if not better! Using both the color detail from the negative and my father's personal print of the film as a reference, we were able to carefully match the look and feel for each scene throughout.
