Oliver Stone made a mess of the Tony-sister theme in his reworking of the Scarface story. Stone always gets too kinky when it comes to sex in his scripts (see the scene between Nick Nolte and J Lo in U Turn). The incest theme is already there in the original Scarface (1932), but Stone takes it over the top in the 1983 version. It should have remained an understated theme. De Palma should have demanded that Stone rewrite the "F**k me tony" scene.
