Before McQueen died he became a Christian. I saw an interview with a pastor that says McQueen just walked into his church one day and started asking him about the gospel, and he became a strong Christian.
There was also a story that when his body was found, he had his bible open and had been reading it.
He was also a conservative.
“Steve McQueen was a pilot, not a celebrity, at Santa Paula Airport
Steve McQueen was an ex-Marine, a political conservative, pro Vietnam, carried a pistol (he learned he was on Charlie Manson’s list), became (at this airfield) a born again Christian, and he mysteriously used to demand big lots of things like electric razors and bluejeans from movie studios when he was filming. It was revealed that he sent the lots of stuff to a boys home that he had lived in, he made visits to the home all of his life and answered every letter that the boys ever sent him. WM”
