Even a mammoth of a movie like Avengers: Endgame has some footage that was filmed, but never saw the light of day.
It's hard to believe that a film with a 181 minute run time has anything else to give us, but rest assured that there are probably another three hours (and then some) of recorded scenes that were left on the cutting room floor.
The same goes for dozens more famous comic book movies, but only a select few had entirely different endings made that fans have never seen. The following ten films inspired by comics all have alternative endings out there somewhere, but good luck if you ever want to track them down.
Some were changed because they didn't match the overall tone of the movie, some disappeared because they would have tipped the film over into a new age rating, and some were left out because of very real world events.
They all share one trait though - no matter how badly you want to see them, the chances are that your wish will never come true.
What a bunch of teases we are.
10. A Bat Callback - Batman Forever
Tim Burton's Batman movies have not aged as well as you think they have.
They're very silly, the plots are all over the place, and Michael Keaton's batsuit is utterly absurd. He can't move his neck!
Still, at the time, they were revolutionary. Nobody had thought to present the Caped Crusader in this way, laying the groundwork for Christopher Nolan to completely reinvent the character once again with his trilogy.
As for the Batman films in-between Burton and Nolan, well...
1995's Batman Forever, which Burton produced but did not direct, was a step backwards towards the more cartoony superhero films of the 1960s.
Jim Carrey as The Riddler anyone? No? Didn't think so.
The film is a complete departure from what came before it, which is strange when you think that it almost ended with an homage to Burton's work.
A scene was filmed showing Val Kilmer's Batman and Chris O'Donnell's Robin staring up at the Bat-Signal a la Michael Keaton's Bruce Wayne at the end of the original Batman film.
Would this have changed the overall perception of what was a middling Batman film? No, but it would have been kinda neat.
