OK, I'll grant that Cary Grant (ne Archibald Leach) was Hollywood's handsomest
leading man — and for the long span between the early screwball comedies (playing opposite Katharine Hepburn, Irene Dunne, and Rosalind Russell) and the later thrillers (with leading ladies Ingrid Bergman, Grace Kelly, Eva Marie Saint, and Audrey Hepburn).
But who is number two? I would nominate the Clark Gable of "It Happened One Night," "GWTW," and "The Hucksters." How about you? Would you choose the young Gregory Peck of "Ten O'Clock High," or maybe Robert Mitchum in "Out of the Past," or William Holden in "The Bridge On the River Kwai"? Or Paul Newman, Warren Beatty, Burt Lancaster, Steve McQueen, Dana Andrews in "Laura," and I'm sure I've overlooked an obvious contender on the order of Clint Eastwood, Marlon Brando, Robert Redford, Woody Allen, George Clooney, and a whole raft of British actors from Laurence Olivier to Errol Flynn.
