James Dean came to Hollywood when he was eighteen, hoping to get into the movies. At first, he was not successful at all. Then he went to New York. He got a part in a play and was seen by the great director Elia Kazan. Kazan was planning the movie East of Eden and realized Dean would be perfect for one of the main roles.

By this time, Dean had already had a reputation and was difficult to work with. He then went back to Hollywood to make East of Eden and then made two more movies, Rebel Without a Cause and Giant. He almost always wore the same overcoat and jeans and he had hardly any friends at all. “If he didn’t like you, he wouldn’t even give you the pleasure of his anger. You could be in the same telephone booth with him, but you wouldn’t exist,” someone who knew him said later.

In spite of his poor eyesight, he loved driving fast motorcycles and even faster sports cars. A few days after he finished Giant, on September 25, 1955, Dean went for a drive in his new Porsche. It was evening and the light was poor. Dean was not wearing his glasses. Suddenly, he saw a car in front of him. It was slowing down and trying to turn off the highway. Dean tried to slow down too, but it was too late. He hit the car at high speed and was killed immediately.

A few years later, a New York salesclerk wrote a book called Jimmy Dean Returns in which she claimed that she was in contact with Dean from the other side of the grave. Half a million copies of the book were sold. It was only the beginning of a strange legend(传奇) that goes on, even today.
