Today is Oct. 21, 2015, which means Marty McFly (Michael J. Fox) and Doc Brown (Christopher Lloyd) have officially landed their DeLorean time machine and are in mad pursuit of their future (fictional) selves.

But in reality, those two actors have real future selves and so does the rest of the cast. Even though the film franchise tried its best to predict what they would look like or what they would have achieved at this point in time, the results have varied, according to USA Today.

Fox himself has had quite a career, not only starring in the "Back to the Future" franchise and several other hit films but also making progress in the TV arena. Before he was Marty McFly, he had already set his acting career into motion starring as Alex in the sitcom "Family Ties."

After the "BTTF" franchise, he also starred in "Spin City," a hit sitcom he would later have to leave to deal with health issues. In 1991, he was diagnosed with early onset Parkinson's disease, and it later affected his daily life to the extent that he could not work. He did make a short comeback though, playing in a recurring role on "Rescue Me" and with his own show "The Michael J. Fox Show."

Lloyd went on to star in a few notable roles in some family films. Those include "Dennis the Menace" and "The Pagemaster."

Lea Thompson played Marty's mother Lorraine, and she was made to appear incredibly old and fragile. But that is quite different than what she really looks like now. She has had quite a career spanning the last 30 years, appearing in her own NBC sitcom, "Caroline in the City," and a few other select film roles.

Tom Wilson (Biff Tannen) also moved on to star and co-star on a few projects, which includes "Freaks and Geeks," "The Heat" and "Spongebob Squarepants."

Crispin Glover appeared as Marty's dad George in the original film but was replaced with a lookalike actor in the sequel. He has also seen some success in his career, appearing in films like "Knave of Hearts," "Charlie's Angels: Full Throttle" and Tim Burton's "Alice in Wonderland."
