Big one I'm dissapointed wasn't made was 'Good Omens', based on the novel by Neil Gaimen and Terry Pratchett (highly recommended if you like to read ). It was going to be a Terry Gilliam movie. Screenplay was all written, they were just trying to get funding though due to the amount of effects needed they had to look to American companies and they weren't interested
If American Mcgee's Alice ever happens. I want it as an animated feature(although, I dont see it happening since parents will be stupid enough to think of it as the Disney version of the story).
Speaking of Terry Prachett. I remember reading that Disney was at one point interested in developing a 2D animated film of the Discworld novel Mort. They ended up not doing it since they couldn't afford the rights. Which was a shame since Mort is my favorite book in the Discworld series, and a few of my friends who worked for Disney told me it would have been true to the book.
Yeah, Disney was planning on doing Mort. However, when they were trying to get the rights to the book. They ended up getting four other Discworld books(or so i'm told). When Disney just wanted mort. Needless to say, thats what put an end to mort.
Speaking of stop-motion, there was a fan-made trailer of American McGee's alice. It was so good that everyone thought it was the trailer for the next game. Even the creator(despite saying it wasn't the game trailer) was impressed by it.
As for movies. I got more animated films to mention that I wish that happened.
Howard the duck- Yeah, the live-action dud that was known by star wars creator George lucas was originally convinced as an animated feature. Universal axed that idea so they can have a live-action movie for the summer release. It was mentioned in the DVD commentary. As much as Disney now wants to pretend Howard never happened. I still wish that one day Howard the duck will get the justice he deserves.
Brad Bird's The Spirit- Back in the 80's, Brad Bird helped out on an animated trailer based off of Will Eisner's comic The Spirit. Will Eisner loved it so much that he wanted an animated feature based off of his comic. Brad wrote a script(which has been described as very faithful to Eisner's comics) and was pitched to Hollywood. However, they liked it, but they rejected the idea of it being animated over live-action. To think. How animation could have been changed if this happened. It would have been a much better movie than the infamous Frank Miller disaster.
Bobby's girl- Also in the 80's. Badboy animation director Ralph Bakshi saw how talented a young artist by the name of John K(who would later be known for creating Ren and Stimpy) was in the terms of cartooning. They both got along well and both agreed that animation was in the shitter at the time. When they were doing New adventures of Mighty Mouse. Ralph and John came up with the idea of an animated feature(which I can assume would be PG-13 rated) called Bobby's girl. It was supposed to be a parody of the teen genre films at the time. Like stuff like The Breakfast Club. I spoke with John K about this a couple of years ago. He said to me that the movie went through a ton of scripts(actual movie scripts, since Tristar wouldn't allow The Bakshi Studio to use storyboarded scripts). Each one that Ralph and John looked over, they took out the parts they found funny and put it in the final script for the film. There was later a fallout with the producer at Tristar(who would later get fired, and the people who replaced him couldnt see the idea of it working out well since it was "different" from most teen comedies). I wish this happened the most, since Ralph Bakshi and John K are both of my favorite cartoonists.
Frank Sinatra, Dean Martin, and Bing Crosby were planning on starring in a film about Jimmy Durante, Lou Clayton, and Eddie Jackson. It was going to be directed by Frank Capra. I was so disappointed when I found out it never got made.
I have read before that Raimi at one time had a post-apocalyptic Evil Dead 4 idea, I can never seem to find more about that. It was a long time ago when I saw that too, I always envisioned it as Army of Darkness meets Mad Max.
Much as Golden Compass (grrrrrr....it will always be Northern Lights to me) sucked ass and stripped out a lot from the book, I was looking forward to seeing if they redeemed themselves with The Subtle Knife and The Amber Spyglass. Alas, this will never happen now.
...I kinda wish they'll do a proper adaptation of Northern Lights now, with all its religion-based plot intact.
