In the great Oscar winning best picture Patton, Karl Malden as Omar Bradley explains the difference between himself and George C. Scott. Malden is a professional soldier trained to do a job, whereas Scott just lives for the action because he loves it. That's what Steve McQueen is as a hotshot bomber pilot who has a crew of Karl Maldens who just want to do a job and get home alive.
Oddly enough a year after The War Lover came out Steve McQueen would play another hotshot pilot in The Great Escape. A pilot who's been grounded and temporarily enjoying enemy hospitality. I wonder how the two McQueens from The War Lover and The Great Escape might have viewed each other.
McQueen's co-pilot Robert Wagner dislikes McQueen's living on the edge style though he knows this guy has the skill to back up his brag and has done so. But things could be going further south in their relationship as McQueen makes a play for proper British woman Shirley Anne Field whom Wagner likes as well.
It's an interesting role that McQueen has and he pulls it off. He's not a nice person, but you can't help rooting for him. Especially in that last close run thing he attempts at the close of the film.
The War Lover is a good war picture and will satisfy the fans of Steve McQueen who are still legion in this world.
