Milles Teller, Josh Trank almost had a physical fight on set?

Director Josh Trank and actor Milles Teller, who played the lead in his "The Fantastic Four", reportedly got close to a fist fight during the film's shooting.
The 31-year-old filmmaker was the one, who insisted on Teller playing Reed Richards/Mr Fantastic, but during the shoot the equation between the duo turned sour, reported Entertainment Weekly.
On set, Trank was apparently said to be abusive and insulting to the crew and cast. The studio did not want the "Whiplash" star, but Trank fought for him.
Then he ended up almost fighting Teller, who has a reputation for sarcasm and recalcitrance while working.

It is said that at one point, the conflict nearly became physical, with Trank and Teller chest to chest, daring each other to throw the first punch but neither did.
