After laying down their firearms, the couple take a stroll. At this point the McQueens had been married for seven years and had two young children, but the spark between them was still very much alive. "They were always necking!" says Dominis, who also remarked upon their childlike way with each other in notes he filed for LIFE's editors back in '63: "They chase each other around," he wrote, "as though it were going out of style."

Trailing Steve McQueen was Dominis' first Hollywood gig. "I liked the movies, but I didn't know who the stars were; I was not a movie buff," Dominis, now 88, tells LIFE.com. But he got the assignment because he and McQueen shared one vital passion point. "When I was living in Hong Kong I had a sports car and I raced it," Dominis says. "And I knew that Steve McQueen had a racing car. I rented one anticipating that we might do something with them. He was in a motorcycle race out in the desert, so I went out there in my car and met him, and I say, 'You wanna try my car?'" Later the two of them would zip around Los Angeles, including Sunset Boulevard (pictured). "We went pretty fast — I mean, as fast as you can safely go without getting arrested — and we'd ride and then stop and trade cars. He liked that, and I knew he liked it. I guess that was the first thing that softened him."
