 According to numerous biographies and documentaries on Steve  McQueens life, one of the first signs of problems relating to the  cancer in his lungs (which would claim his life) occurred when  shooting a scene in which McQueen is running down the street and  turns a corner. When the director yelled, "Cut!," McQueen didnt  come back around the corner. McQueen was found leaning against a  wall trying desperately to catch his breath.
