When filming First Blood, Stallone is alleged to have violently clashed with the director, Ted Kotcheff, at one point breaking three of his ribs. And he objected so vehemently to the original ending where Rambo committed suicide, he was sued by the studio to ensure he would return to the set and film it. 'After the first screening in Las Vegas, I went out into the alley and threw up. It was all wrong. Artistically totally correct. Emotionally totally wrong.’ The ending was reshot with Rambo getting to live. 'That’s the difference. It’s not naturalism. It’s dramatic realism. The films are realistic fantasies. Bullets are easy. You can buy ’em. Emotions are not. They’re priceless.’
