I am one of the few people actually excited for the new Fantastic 4 movie. I believe Miles Teller and Michael B. Jordan are going to knock it out of the park. But, I want to get some creative juices flowing and take a swing at my very own casting.
To start it off the villain, Doctor Doom:
I am choosing Jared because of his role as Sam Winchester on Supernatural. He is able to switch from being good and bad at the drop of a hat, it's honestly amazing. Early on in the show, he portrays Lucifer and kills it! If he used that kind of demeanor as Doom, he would go down as one of the best movie villains ever.
Now for Reed Richards, AKA Mister Fantastic:
Tennant would be so good as Reed Richards. Just watch him as the tenth doctor. A quirky genius who doubles as a great leader and he's always full of energy. He was made for this role!
Now for Susan Storm AKA Invisible Woman:
There are two big factors in this casting choice the first and most important is that she already has chemistry with Tennant, considering they are married in real life. And the other is she is a ringer for Invisible Woman from the comics.
Now for the Johnny Storm AKA Human Torch:
Chris Pratt is one of the biggest stars in Hollywood, as well as already being in the MCU, so for Fox to sign him would be practically impossible, but he'd be awesome! Take his comedy from Parks and Rec and his bad boy rebel sarcasm form Guardians and set his ass on fire, you have the Human Torch ladies and gentlemen!
Now last but not least, Ben Grimm AKA The Thing
This guy is a total bad ass on Teen Wolf. His physical acting wold be perfect for The Thing, and the transformation would be more natural since he is constantly transforming into a werewolf on Teen Wolf, so give him a contract FOX!
