If you want to know how much screen time Jamie has in Fantastic Four, here you are:
7:26-11:00
11:01-12:34
36:33-38:15
38:16-45:43
Those are where we can see him in human form. After that he becomes The Thing, and they change his voice.
And I did this. The Eagle boys go to the Space, I think it will be better than both Jupiter Ascending and Fantastic Four.
