Dead Ringers

Elliot (Jeremy Irons) and Beverly Mantle (Jeremy Irons) are identical twins and highly successful gynecologists. Elliot, the more aggressive and confident of the two, seduces women who come to the Mantle Clinic. When he tires of them, the women are passed on to the shy and passive Beverly, unaware of the substitution. When Beverly becomes attached to the troubled actress Claire Niveau (Geneviève Bujold), it upsets the equilibrium between the twins. The actress' rejection of Beverly sends him into clinical depression, prescription drug abuse and delusions about "mutant women" with abnormal genitalia. Due to the twins' codependent relationship, Beverly's breakdown eventually causes Elliot to follow.
