Super cool Steve McQueen as the legendary SF cop Bullitt (1968) calmly sets the ground rules with the much underrated in my opinion supporting actor and TV “The Man from U. N. C. L. E.” Robert Vaughn as Walter Chalmers, an ambitious politician who gets in the way of a police investigation: “You believe what you want. You work your side of the street, and I’ll work mine.” Catch the touching Oscar nominated performance of Mr. Vaughn (as society rich boy Chester Gwynn outcast by family snobs when he is disabled in the Korean War) in The Young Philadelphians (1959) and close friend screen icon Paul Newman comes to his rescue. What a successful film career to collaborate with McQueen and Newman!
