Fan Casting The Fantastic 4

(Inspired by the youtube series Fanscription and decided to explore What If Fant4stic was better, since I'm going with a sort of hybrid of the Jeremy Slater Script and with some of my own ideas.) Four scientists set to the unknown to discover, but a tragic turn of events causes them to gain new and special abilities. These chain of events cause them to open a door to a new dimension (The Negative Zone). They soon to realize that their actions have extreme consequences when a creature from the other dimension comes to conquer our world and without the protection of the fallen Avengers it is up to them to save our world.
