In 1972 Charlie Chaplin was allowed back to America to receive an honorary Oscar, 'for the incalculable he had on making motion pictures the art form of this century'. That's what the Academy was always for - to blur the equation enough so that profit and fame could be called art.

I dislike The Exorcist, and I found it a warning sign of the dangers in a furious cinematic talent putting the audience through it (a Hitchcock phrase) without purpose, or without the nagging moral anxiety that activated Hitch. You see, I don't think William Friedkin believes in the Devil, or cares about him. I think he found exorcism a pretext for a gross-out and he calculated there was an audience for it, or a crowd ready to be challenged. Maybe I'm too much of an atheist to stand religion being so thrashed.

Louis B. Mayer is one of those with a claim to posessing the equation... he began to buy up nickelodeon arcades in the years before the First World War in and around Boston. He had noticed that people liked going into the dark to see the light... the appeal of the movies is beyond the sensible, rational or the hard-working. Going into the dark, afte centuries of progress in which mankind has staggered toward artificial light, smacks of delicious perversity.

I regret the way that America has elected to make films for its bluntest section of society and in ways that flatter them, and we have to recognize how much that is being done for money. We have to find another way of measuring ourselves. And film is one of the few ways that might be done.

What guided Chaplin was the proper protection of self-interest (or craziness). So Chapling, Douglas Fairbanks, and Mark Pickford, with DW Griffith and William S Hart, made an alliance, called United Artists, whereby they would own a distribution company that would market their pictures, allowing them a greater return than if they leased the movies to some outside distributor.

The discrepancy between what actually happened and the version of what happened provided by sources is an enormous gray area.

The capacity for loving strangers, whether one thinks of them as fictional beings or stars one will never meet, is a profound reflection on the new consciousness whereby every individual leads his or life while aware of all the billions of other people on Earth. Perhaps it is a fantasy or a fallacy that we can feel for so many strangers. Perhaps it is a mask for selfishness. But no matter the modern stress on special effects, there isn't a sight in movies as momentous as shots of a face as its mind is being changed. And only movies have allowed that.
