Summary
- Cult classic sequels like The Mask 3 and League of Extraordinary Gentlemen 2 have the potential to capitalize on the superhero film dominance if given another chance.
- The Amazing Spider-Man 3 and Spider-Man 4 could provide redemption for previous iterations and further explore beloved characters like Rhino and Peter Parker.
- Movies like Spawn 2, Hellboy 3, Constantine 2, and Dredd 2 have the potential to improve upon their predecessors with modern CGI and storytelling techniques, satisfying fans longing for sequels in these franchises. The Incredible Hulk 2 could also provide a much-needed standalone movie for the iconic character.
Though the MCU (and, perhaps soon, the DCU) can confidently claim that their never-ending cavalcade of comic book movie sequels are among the best and most in-demand, there is a list of long-delayed sequels that we are all still wanting to see. Whether planned or not, it feels like too many sequels have been left hanging in the balance, their development halted by myriad roadblocks, foremost among these being the lackluster performance of their predecessors. In this new age of superhero supremacy in cinema, however, there is ample opportunity for these cult classics to capitalize.
When it comes to reviving franchises, the new norm is the reboot route. This has, of course, led to some of the best Superhero movies of all time. Some notable failures to resuscitate Superhero franchises, however, have helped to prove that this isn't always the correct tonic – especially when the IP wasn't dead to start with. Whether a continuation of stories left hanging or a chance to rectify past mistakes, these are the sequels that never came, but ones we still want to see.

The Mask is one of Jim Carrey's most iconic roles, with its success being largely down to his larger-than-life portrayal of the titular character. Only a handful of actors – Carrey foremost among them – that could pull off the character first depicted in Dark Horse Comics. To create a sequel in Son of The Mask without him, then, was a huge misfire that can only be rectified by a return to form facilitated by Carrey's involvement once more. After all, if Carrey was happy to reprise his role in Dumb and Dumber To years after the original, then perhaps he would give this iconic comic book character another spin.
