描述:　　In Cecil B. DeMille’s 1920 comedy Why Change Your Wife? Gloria Swanson (DeMille’s regular leading lady of this period) as Beth, a respectable and rather prim wife who discovers that husbands don’t necessarily want their wives to be respectable and moral. It’s not that he doesn’t love her; he just wants a little romance in his marriage, and when another woman comes along who offers him the excitement he craves, he inevitably strays. And divorce inevitable follows.　　Beth then has a sudden revelation – maybe it’s not only true that men like shameless hussies, but maybe it’s also true that shameless hussies have quite a lot of fun. So she decides to transform herself into a sexpot.
