The Hollywood actor plays mathematician Ian Donnelly in the sci-fi drama - which is based on Ted Chiang's short story "Story of Your Life" - and he was amazed how director Denis Villeneuve had managed to bring the script to life, admitting he was delighted to be a part of the project.
"When I saw the movie for the first time, it wasn't done; the sound wasn't done, the visual effects weren't done. You saw the aliens once or twice. It was really kinda rough. But you got a sense of the scope," Renner said.
"I ran out, fell in the parking lot and cried my eyes out. I said, 'I can't believe I'm a part of this. I cannot believe what that guy did with this beautiful scrip'.
