This is a super simple topic from your beloved Devil Man!
Which films do you so, so, soooooo wish had a sequel? There must be some films you wish had sequels, right?
I wish Blade Runner had a sequel. That's one film that Needs a sequel to explain the mysteries of the first movie.
And... okay, it is a trilogy already, but I wish Lord of the Rings had a sequel. The Hobbit will be a movie one day, but I'd love to see a movie of the whole 'Akklabeth' Saga in The Silmarillion. You know how it goes... Sauron gets captured, taken to Numenor, tricks the King, the King sails to some island he isn't supposed to, and BOOM! Numenor gets whipped by the Gods and Sauron loses his body. That would make a great trilogy of it's own (For all the Tolkein fan-boys, yeah, don't get mad at the quick summing up) I wanna see more Tolkein movies! (Alright... they would be prequels, but you get the picture...)
Thats all I can think of for now. What about you?
Oh! And... yeah, you can add a sequel to a film that already has a sequel because... well... then, in your opinion, it is a film that still deserved a sequel, geddit?
Here's another one... I wish Terminator 2 had a decent sequel and not the pile of crap that was Terminator 3. I wish it had a true sequel with James Cameron behind the camera.
