Does Steve McQueen Still Hold the Crown for the King of Cool?

I've never actually watched a Steve McQueen movie before despite him being a legend and known as the King of Cool. But that stops now with my review of the 1968 Thomas Crown Affair. I was originally going to cover the 1999 Pierce Brosnan version but I already covered quite a lot of his Bond movies recently. So it's time to get a bit nostalgic. So what is so cool about Steve McQueen?
