Marty McFly is a fictional character and the protagonist of the Back to the Future franchise. He is a high school student living in the fictional town of Hill Valley, California, who accidentally becomes a time traveler and alters history after his scientist friend Emmett Brown invents a DeLorean time machine. He was created by Robert Zemeckis and Bob Gale. In the film trilogy, he is portrayed by Canadian actor Michael J. Fox. Back to the Future established Fox as a film star, such was the commercial success and popularity of the film upon its release in 1985.
