Back to the Future...did it change?

Rating: 8/10 (25 April 2017)

Back to the Future was released in July 1985 and is the story of Marty McFly played by Michael J. Fox. Marty ends up going back in time with his friend Doc Brown, played by Christopher Lloyd. Doc turned his DeLorean into a time machine powered by plutonium. They take the DeLorean back to 1955 and end up meeting Marty's parents, George (Crispin Glover) and Lorraine (Lea Thompson). While in 1955, Marty has to be sure that his teenage parents fall in love to make sure that he can make it back to 1985 alive.
The theme of Back to the Future is the conversation about fate and free will. Are we all on a predetermined path that cannot change or do we have the power to change our future? Marty is able to go back to when his parents first met. As the movie progressed and his time in the past grew, he had to make sure that his parents would stay together to ensure that he had a future to go back to. Was it always supposed to be like that? In the 1955 that his parents remember before he was born, did he actually come from the future to keep them together? Or did he alter history? This is the question that is addressed in almost every movie about time travel. Do the effects of what you do in the past ripple through time toward the future?
The effects of the movie were excellent for their time. The special effects used to transport the DeLorean back to 1955 made it look possible. Doc is the perfect mad scientist for the job. The DeLorean is just as crazy as him. With the switches and flashing lights, it is exactly what you would think a time machine to look like. The camera angles that are used in the movie give the viewer the experience of traveling through time. Cameras with the outside of the DeLorean in view during the time travel reveals the special effects used by the production to make it look like the car is actually traveling through the space-time continuum.
Director Robert Zemeckis does a great job with the film to make the viewer think about the effects of the past on our future. If the past would change because of someone using time travel. Would it effect the future immediately? Or did the future already know about that change so nothing would change that we know of?
