What ever “it” is in terms of masculine coolness, e.g., women love him,
guys want to be like him...
Steve McQueen had a mega-dose of it.
I saw one documentary on him on PBS in Los Angeles over five years
ago...the guy was even trying to go deeper in literature and philosophy
before he exited the scene.
Maybe he’d never have made it to “renaissance man”, but he was
giving it a good try.
