Catherine Zeta-Jones
Chicago
Maybe it's a little unfair to include Zeta-Jones on this list because of her musical-theater roots, but she's too good not to include. A classic Broadway belter, she easily out-sings (and out-dances) her costars in Chicago, alternating between brassy (''All That Jazz''), comical (''I Can't Do It Alone''), and sweet (''Nowadays'').
