In “Back to the Future”, Marty McFly, a high school student, accidentally travels back in time when his scientist friend Doc Brown sends him to 1955. Altering past events, Marty has to ensure his parents fall in love and save Doc’s life or else the life he knows will cease to exist. In the scene “1.21 Gigawatts”, Doc watches his future self on T.V. They both realize that in order to power the time machine (the DeLorean) without plutonium, it will require the amount of electricity from a bolt of lightning. When Marty shows Doc a future newspaper clipping that recounts a lightning strike at the town’s courthouse, the exciting adventure of going back to the future begins.
Some diegetic sounds include the sound of the T.V. as Marty and Doc watch, and the characters’ excited and anxious dialogue. After Doc mentions the lightning bolt, orchestral music begins to play in the background. It crescendoes in sound and intensity, climaxing when Doc says he’s sending Marty back to the future. This is the non-diegetic sound. The music creates a suspenseful mood, telling the audience that something exciting is about to happen. The odd rhythm of the strings also creates an anxious mood.
I have never watched this film before but it seem so interesting. “The Flash” from Netflix goes hand to hand with this movie. I could see that the show definitely took ideas from “Back to the Future”. I agree that the non diegetic music created a suspenseful mood. I wrote my blog about “Get Out” and I see that the both movies created an anxious dialogue and suspenseful mood.
