7 Comic Book Movie Endings That Really Needed A Sequel

5. Hellboy II: The Golden Army

Hellboy II ended not just with the Golden Army being defeated, but its titular demon ready to take on his biggest challenge yet: parenthood.

He and Liz both resigned from the B.P.R.D, after which she revealed she was pregnant with twins. It finds the team having to seriously contemplate their future, but with the wider ramifications of the choice between humans and magical beings left open, which indeed would've been explored in the sequel.

Simply doing a timeline of Hellboy 3 being on and off again would be an exhausting task, with Guillermo del Toro attempting multiple times over the last ten years to make it happen, until eventually it was announced the franchise was being rebooted instead, with a ripped David Harbour taking on the lead role. It means we'll never get the conclusion to del Toro's trilogy, for which he had some epic plans, with the director revealing in a Reddit AMA:

"...The idea for it was to have Hellboy finally come to terms with the fact that his destiny, his inevitable destiny, is to become the beast of the Apocalypse, and having him and Liz face the sort of, that part of his nature, and he has to do it, in order to be able to ironically vanquish the foe that he has to face in the 3rd film. He has to become the beast of the Apocalypse to be able to defend humanity, but at the same time he becomes a much darker being. It's a very interesting ending to the series."
