Many movies and TV shows have graced the Blu-ray disc format since it was first introduced to the public. However, not everything has, same with most formats in reality, but that doesn't mean that there isn't some movies that are wanted on Blu-ray. Here are a selection of a few that aren't as of writing available on Blu-ray.
Bad Boys 2
The Iron Giant
Ah yes, The Iron Giant, the 1999 animated movie that was based on the book The Iron Man, not to be confused with Marvel's Iron Man. The Iron Giant is a massive robot, and in the 1950s, when the story is set, it's a big deal. I could go on all day as to why The Iron Giant is a great movie, and worthy of a Blu-ray release, but I won't. Instead, look at that poster which is the DVD cover art, it's sublime. Brad Bird directed The Iron Giant, and he went on to direct The Incredibles, the one Pixar film that needs a sequel. Those are two things that should happen. Will they? Only Warner and Disney know.
Star Wars: The Original Trilogy
However, it is extremely unlikely, not just because of the already released Blu-ray version, but because of Disney's acquisition of Lucasfilm. This is because Fox still retain the distribution rights to the original movie and I imagine they would want a big percentage of the royalties for any re-release, even though Disney and Fox know that fans would pay a premium for the original theatrical versions on Blu-ray. Oh well, at least we can look at the great posters I put up above which came from the talented Olly Moss, who also did the cover art for Resistance 3, which is also great.
Mighty Morphin' Power Rangers: The Movie
I know four is a strange number but it's an even one and so that is all I can think of for Blu-rays that don't exist but they should. One day, maybe... probably not.
