"We are dabbling in the unknown with dangerously potent tools." That is from the magazine article on which this film is based: "Ten Feet Tall," by Berton Roueché, from his brilliant "Annals of Medicine" series in The New Yorker (10 September 1955). Before I watched this Nicholas Ray film for the 2nd time, I read the original article and was quite astonished to find that the film is both faithful and unfaithful to the truth, and in surprising ways.

The most stunning thing is how quickly Ed (James Mason) is affected by the cortisone he is given to treat his rare and dire disease, a typically fatal inflammation of the arteries. I doubted that the derangement that made him feel "ten feet tall" would have happened as quickly as in the movie, which needs to get the plot going.

Well, I was wrong. The Long Island teacher on whom the article was based had a psychotic break almost as soon as he started taking the corticosteroid. The entire episode of his psychosis lasted only three weeks, but during that time, he was a terrifying presence. His threatening, dictatorial behavior toward his wife and son, not to mention his colleagues, were, yes, exaggerated for dramatic effect (especially the scorn he heaps on his wife), but Mason's portrayal is strikingly close to the real teacher's experience: the madly impulsive spending, the manic speeches and wild philosophical brainstorms, as well as his demand to be absolute ruler in his home and his unveiled contempt for everyone because they're all fools, except him.

James Mason, Barbara Rush, and Walter Matthau do solid work, as does Christopher Olsen, a child actor who also worked with Hitchcock, Cukor, and Sirk. Much has been said about Nicholas Ray's choices as director, and what interests me most is the ways he chose to be unfaithful to the original story.

First, location. Although the actual teacher lived in Forest Hills in Queens, "Bigger than Life" is set in a nameless suburbia, and it was filmed it in color for the big screen even though it's a domestic drama of the sort that was still shot in black-and-white at the time. Much has been made of those two choices, which are taken to be a commentary on stifling, conformist suburban lives in the 1950s. But I think Ray's decision to move it to a more typical American landscape than New York City, and to treat it as a big-screen color feature, had to do with the dramatic weight of the subject: drugs that save lives can cripple them at the same time, and the film has strong references to the deep shame that was (and to some extent still is) attached to mental illness. The wife won't even hear the word psychiatrist.

Second, the doctors. In the movie, Ed tricks doctors and druggists to increase his intake of cortisone-- if he feels ten feet tall on one pill, why not take two? In the true story, it was the doctor who increased the dosage, but did not schedule frequent follow-ups, even though he knew the risks from side effects. That's a much more damning situation than a mentally ill outpatient doubling his own dosage. So why shift the blame from doctor to patient in the movie? Here's a possibility: There was concern about blowback from pharmaceutical companies and/or the American Medical Association. But on the whole, I can see why "Bigger Than Life" has come to be so highly regarded, if not sufficiently well known.

Back in 1956 this must have been a very daring flick indeed. Of course it has dated and today it packs less of a punch but it still remains a very sincere film anchored by a superb James Mason performance. Walter Matthau is similarly top rate though in a smaller and less flashy role. The direction is absolutely mesmerizing and I only felt slightly uneasy about the psychiatric approach of the day and the flashing red screen reflecting Mason's mental disintegration which was so in fashion in films of the time.

Even so, it was not enough to spoil the pleasure afforded by the many good aspects in this movie that I found quite riveting and intelligent for the most part. The bit where Mason snips the phone cord is as frightening as it is memorable, to me the highpoint of a honest yet never predictable work.
