Another thing about the two movies are the romantic relationships in it. The key relationship in
Casino is, of course, the unhappy marriage of Ace and Ginger Rothstein. Unhappy relationships are usually the standard for Scorsese movies. And Scorsese builds up this relationship, using the theme from
Contempt as a leimotif and having De Niro, in his first scene, saying that ultimately you have to trust your spouse for any such relationship to work. Yet if you leave aside the "contract movies" like
The color of Money and
Cape Fear, and the relationship Harvey Weinstein insisted on inserting in
The Gangs of New York, this may be the least interesting romantic relationship in all of Scorsese movies. Granted that it is based on a real marriage, and granted that Rothstein has his own problems, there is no good reasons why Rothstein should stay with such an obviously treacherous and unstable gold-digger.
By contrast, the three relationships in
Heat are much more plausible (Pacino/Venora, Kilmer/Judd and DeNiro/Brenneman). That they should all come to a crisis in the course of the movie is much more understandable since the relationships all under the same stress (two of the man are tying to carry out a big heist and the other man is trying to stop it).
