In a world full of multi-billion-dollar franchises it's clear studios are becoming a little less, let's say, selective.
This desire to create the next big money spinner has lead to a string of generic by-the-numbers blockbusters or, even worse, lacklustre sequels and remakes of once great franchises. All of which leaves audiences to ponder just one question. Why?
However, despite their seemingly non-existent standards, Hollywood has occasionally been known to let a few potentially awesome projects fall through the cracks into the fiery depths of development hell.
Whether it be a case of studio cost-cutting, disagreements over creative control, or seemingly impossible filming considerations, there are plenty of reasons for even the greatest of concepts to end up on the proverbial cutting room floor.
So, if you've ever wondered why Quentin Tarantino's long-awaited Pulp Fiction prequel never reached the big screen, or why The Beatles were once in talks with Stanley Kubrick to appear in a Tolkien adaptation, now is your chance to find out.
12. The Vega Brothers
Background: A Quentin Tarantino prequel featuring Pulp Fiction's Vincent Vega (John Travolta) and Reservoir Dog's Vic Vega (Michael Madsen) as the eponymous Vega brothers. The film was set to explore the pair's exploits in Amsterdam prior to Reservoir Dogs and lead to the discovery of the famous "Royale with cheese".
Why It Didn't Happen: Despite the enormous success of both Reservoir Dogs and Pulp Fiction, Tarantino moved on to other projects and this ultimately resulted in both Travolta and Madsen becoming too old for a prequel to seem realistic.
Will It Ever Happen? Directed by Quentin Tarantino? No, but another director could revive the project in the future, cast younger actors and ride on the coat tails of the Tarantino brand.
There is also the option to de-age Madsen and Travolta which, considering Captain Marvel's success of taking Travolta's Pulp Fiction co-star Samuel L. Jackson back to 1994, is perhaps not that unthinkable.
