@Pantherpool - he's my backup if they can't get Efron, but it looks like they're making more Power Rangers movies so he might be busy between those two properties alone (Stranger Things and Power Rangers, that is).

@Pantherpool - Glen Powell is my pick for Johnny, he can play a man child really good.

@Gandressmex - Glen Powel would be a GREAT Human Torch. He knows how to be a douchebag/funny guy.

@Jaspion - I'm Genuinely floored because I fancasted Garfield as Johnny Storm too years ago.

My dream cast for the MCU Fantastic Four:

Clive Owen as Reed

He has the charm and the acting chops to sell Reed and just looks like he fits as someone named Reed Richards.

Noomi Rapace as Sue

She has the great acting range to pull off a strong scientist and I think she and Clive could work off each other really well and have good chemistry as Sue and Reed. Plus she is a phenomenal face actress for her fight scenes using her powers.

Andrew Garfield as Johnny

I could 100% buy Andrew and Naomi being brother and sister, Andrew looks like a Johnny and we all know he has the charisma, charm and snappy line delivery needed for Johnny Storm. Obviously he's older than Peter Parker but I think they would still be hilarious buddies together.

Mel Gibson as Ben

This is my favorite of my fan cast. He has those big blue eyes and that iconic gravelly voice, perfect for Ben. And to top it off, I could really see Mel and Clive as buddies as Reed and Ben.

I think these 4 would have phenomenal on screen chemistry with each other and enough star power and acting chips to effortlessly carry a Fantastic Four film in the MCU.
