<human>: Cameron Crowe was born in Palm Springs, California. His father, James A. Crowe, originally from Kentucky, owned a real estate and phone service business. His mother, Alice Marie (nee George), "was a teacher, activist, and all-around live wire who did skits around the house and would wear a clown suit to school on special occasions." She worked as a psychology professor and family therapy and often participated in peace demonstrations and causes relating to the rights of farm workers.

When Rolling Stone moved its offices from California to New York in 1977, Crowe decided to stay behind. He also felt the excitement of his career was beginning to wane. Crowe appeared in the 1978 film American Hot Wax, but returned to his writing. Though he would continue to freelance for Rolling Stone on and off over the years, he turned his attention to a book.  At the age of 22, Crowe came up with the idea to pose undercover as a high school student and write about his experiences. Simon & Schuster gave him a contract, and he moved back in with his parents and enrolled as Dave Cameron at Clairemont High School in San Diego. Reliving the senior year he never had, he made friends and began to fit in. Though he initially planned to include himself in the book, he realized that it would jeopardize his ability to capture the true essence of the high school experience.  His book, Fast Times at Ridgemont High: A True Story, came out in 1981. Crowe focused on six main characters: a tough guy, a nerd, a surfer dude, a sexual sophisticate, and a middle-class brother and sister. He chronicled their activities in typical teenage settings--at school, at the beach, and at the mall, where many of them held afterschool jobs--and focused on details of their lives that probed into the heart of adolescence. This included scenes about homecoming and graduation as well as social cliques and sexual encounters.  Before the book was released, Fast Times at Ridgemont High was optioned for a film. Released in 1982, the movie version lacked a specific plot and featured no major name stars. The studio did not devote any marketing effort toward it. It became a sleeper hit due to word of mouth.  The reviews of Fast Times at Ridgemont High were positive, and the film ended up launching the careers of some of the previously unknown actors, including Jennifer Jason Leigh, Eric Stoltz, Judge Reinhold, Phoebe Cates, Anthony Edwards, Nicolas Cage, Forest Whitaker, and Sean Penn.
