Back to the Future has become a classic from the 1980s and the sci-fi genre to the point where it’s widely regarded as one of the best movies ever made, but it was originally very different as Eric Stoltz was cast as Marty McFly – and had he stayed, Back to the Future, its impact, and Stoltz's career would have been very different. The 1980s saw the release of many now-classic movies from a variety of genres, and the sci-fi world saw many of its movies reaching a lot of success. Among those is Back to the Future, released in 1985 and directed by Robert Zemeckis, with a script by him and Bob Gale.

Set in 1985, Back to the Future introduced the audience to Marty McFly (Michael J. Fox), a high school student and aspiring musician who is friends with Emmett “Doc” Brown (Christopher Lloyd), an eccentric scientist. One night, Marty meets with Doc at the parking lot of a mall where Doc unveils his latest invention: a time machine built from a modified DeLorean and powered by plutonium, which he took from Libyan terrorists. Doc sends Marty to November 1955, but once there, Marty is left without plutonium to return to the future, and so he seeks a younger Doc for help. In the meantime, Marty comes across the younger selves of his parents, George (Crispin Glover) and Lorraine (Lea Thompson), and unintentionally keeps them from getting together, which puts his own existence in jeopardy. Marty and Doc eventually find a way to send Marty back to the future and George and Lorraine fall for each other, ensuring the existence of Marty and his siblings while also giving his family a better future.
