I have just read that 20th Century Fox has chosen actors Jamie Bell, Michael B. Jordan, Miles Teller and actress Kata Mara as the new Fantastic Four.
Teller will play Mr Fantastic (Reed Richards), Mara will play The Invisible Woman (Sue Storm), Jordan will play the Human Torch (Johnny Storm) and Bell will play The Thing (Ben Grimm) using motion capture.
Rumours are that the movie by Josh Trank will have Dr Doom within it, including one that said Dr Doom will be female.
