As a movie fan I watch as many old films as new ones. Every week I watch at least 3 or 4 movies that were shot back in the 40s, 50s or the 60s. And it's amazing how politically incorrect quite a few of them are.

For example, I have watched both the EXODUS (1960) and MUNICH (2005) within the same week and it’s amazing to see the ways in which international politics does influence both screenwriting and the directorial choices.

EXODUS is a flat out pro-Israeli story of the creation of the state of Israel. This almost 3.5 hours long epic film by Otto Preminger is certainly very educational, a fantastic entertainment and does not hide the fact that at least one Jewish underground group, the Irgun, employed terrorism as a technique. However, it is still largely a very sympathetic take on the formation of Israel. There is no question about that.

MUNICH (2005), on the other hand, is full of complicated moral judgments, self questioning and paranoia that is foreign to EXODUS. Although a strong supporter of Israel himself, director Steven Spielberg's approach definitely reflects the changes that our world went through since 1960.

The world of MUNICH is not the clean black-and-white world of the EXODUS. In MUNICH both sides kill for the causes they ardently believe in but what all that struggle does to a man's soul is not clear. The moral judgment is still out there left hanging in the balance of many hard questions.

Or take the SCARFACE (1983), the De Palma cult classic that launched Al Pacino's stellar movie career and still continues to influence the hip-hop culture and videos today.

Even back in 1983 this film was so controversial that it could not be shot in Miami. All the "Miami" scenes were actually shot in Los Angeles. The screenwriter Oliver Stone, knowing the kind of controversy it would create, did not first want to touch the subject but the $300,000 writing fee proved to be too much for a mortal to resist.

Tony Montana is not the only Cuban profile highlighted in SCARFACE. Montana's mother, for example, who totally disapproves his violent drug-dealer career, gives us the "other Cubans" also living in Miami. But due to its incredible violence (remember the chainsaw scene?) and the over-the-top portrayal of The-World-Is-Yours Montana by Al Pacino, most Cubans at the time felt that this movie disparaged the Cuban culture and community and did not want to have anything to do with it. Probably they still feel that way and I can easily understand why.

23 years later not only there would be even more outrage for a film like SCARFACE but probably there would not be even any financing to underwrite such a project, given the prominence and political clout of the American Hispanic community. I think SCARFACE is another politically incorrect film that cannot be produced today.

How about the GODFATHER series? I think the tremendous success of HBO's SOPRANOS has proven that the "Italian-American mafia stories" are still acceptable to a certain degree, especially if they have a modern touch to them (the mafia boss who visits a psychiatrist regularly and worries about his son's performance at school). What's next? A "green mafia boss" who drives a Toyota Prius and leads the crusade against corporations that dump their toxic waste into the ocean? (Hey, there's a million dollar plot for you!)

Another movie that cannot be shot today is THE GETAWAY (1972) starring Steve McQuinn and Ali MacGraw. If you've seen this one you'll remember the scene in which McQuinn actually whacks MacGraw right across the mouth and… she does not hit back! If this was a contemporary film shot in 2006, we would definitely see the female lead character getting back even with the impulsive macho lead. Our modern definition of love does not include an unanswered slap across the face anymore – unless perhaps it is a study in masochism.

Which reminds me of another controversial scene from an otherwise great movie – THE PHILADELPHIA STORY (1940). Remember the scene in which Cary Grant pushes Katherine Hepburn's face rudely and sends her reeling back to the floor (although we don't actually see it)? Try doing that in a modern rom-com and watch the howl of protest from all movie lovers and critics. It would be a sure-fire way to box office disaster.
