#1: CLAUDIA CARDINALE AS MRS. MARIA GRANT IN THE PROFESSIONALS (1966)
There should be little doubt as to why we’ve chosen Ms. Cardinale as the western genre’s hottest actress. First, to appease highbrow critics, she appeared prominently in two of the genre’s best films, The Professionals (starring greats Burt Lancaster, Lee Marvin, and Jack Palance) and Sergio Leone’s epic Once Upon a Time in the West. More importantly, though, the Italian-Tunisian brunette looked like a beauty pageant winner wearing Wild West costumes in both. With her whopping cleavage, Cardinale is the great equalizer between you and your cowboy-movie-loving grandfathers.
