Good suggestion!Before Ben Grimm is the Thing he's typically portrayed as a pretty imposing and tough guy. Played college football, protected Reed when they were in school, fought in the military. Jaime bell was scrawny and Zac Efron is pretty short neither really sell his defining attributes and not even to mention his iconic gruff voice.
And I'm pretty much the originator of the Jesse Plemmons hype around here and he's still my first pick. If they skew older then I'd go Joel Edgerton.
Edgerton would work fine but I also feel he's too old for the age they're planning to give F4 in MCU.
