When Italian film star Sophia Loren arrived to America, she easily managed to impress two men: Frank Sinatra and Cary Grant. The trio appeared in 1957’s action drama “The Pride and the Passion,” which would lead to a real-life affair off-screen between co-stars Loren and Grant.

“Frank Sinatra was very friendly. They became friends and treated her well on the set,” Cindy De La Hoz, Senior Editor of Running Press, told Fox News. “And Cary Grant fell head over heels in love.” Loren, now 83, is the subject of a new coffee table book written by the film historian in partnership with Turner Classic Movies, titled “Sophia Loren: Movie Star Italian Style.”
