Danny Boyle pushed actor James Franco on the set of their new movie 127 Hours by making him work seven days a week.
The Oscar winner is back in the director's chair for the first time since Slumdog Millionaire won best picture and he picked up best Director back in 2009.
This time around he has teamed up with Franco to tell the incredible true story of mountain climber Aron Rolston who had to amputate his lower right arm when he became trapped whist climbing in Utah back in 2003.
Speaking to MSN Movies the filmmaker said: "Obviously the film is incredibly inert in one sense and I thought it would be absolutely catastrophic if it felt inert, so we had this byword that we all talked about, that it was an action movie about a guy who can't move.
"I tried to get James to work seven days a week. We'd force everyone to keep working and pushing, pushing, pushing in the hope that that would bleed into the film, that sense of restlessness.
"We had this idea which I tried to convey to all the actors really, certainly all the crew, that we would make the film at a tremendous pace. I believed it would affect the texture of the film, the feeling of the film."
