1. Star Trek: The Motion Picture (The Director's Edition)
A lot of planning and dedication went into the 2001 Director's Edition of Star Trek: The Motion Picture for its first major DVD release at the time. It allowed for director Robert Wise to finally go back and finish the film he felt wasn't complete during its original theatrical run in 1979. Entirely new special effects were created to either add in an entirely new look for a scene or touch up aspects of the film which were technically unfinished for decades. For all involved, this was a great achievement and made Star Trek: The Motion Picture much more accessible to Star Trek fans. Not only were sections of the original version of the film trimmed up to make the movie drag significantly less than the theatrical cut, but new special effects based on storyboards from 1979 that never saw the light of day were able to be recreated for this definitive version of Robert Wise's sci-fi epic.
In the end, Paramount decided to fall asleep at the wheel once Blu-ray became more mainstream, and in turn did not release this version in high-def. In their defense, one major reason why this wasn't a quick transfer to Blu-ray was because the effects house that created this director's edition only had the new effects remastered in standard definition as opposed to the high-def standard for Blu-ray. If they had been that careless, those new effects would have looked significantly less convincing than they did on DVD, i.e. more pixelated, less smooth. However, nothing was preventing them from having those effects re-rendered and remastered for Blu-ray quality at least in time for the more recent Blu-ray releases of the six original Star Trek films. I would have thought that by the time Star Trek Into Darkness was released in theaters this year, the studio would have jumped at the chance to have this superior version of Star Trek: The Motion Picture released on Blu-ray. I, along with many others were wrong, but maybe they're just holding out for the 60th anniversary of Star Trek to make this a reality. Time will tell, but regardless, this is a film that without question deserved the Blu-ray treatment for its director's edition years ago! Feel free to agree or disagree below and offer in your "top five" list for films that have yet to be released on Blu-ray.
