The final sequence of Back to the Future is nothing more then magical.
For the most part of the film the audience is on edge, watching Marty relentlessly trying to get George McFly and Lorraine Baines (his parents) to kiss at the Under the Sea dance.
And finally, after defeating Biff the bully and conquering the stupid ginger that tries to cut in, George and Lorraine finally kiss.
In celebration, Marty McFly shows 1950's a genre of music they'll come to loathe because of their kids. Rock and/or Roll.
Featuring a shredding guitar solo he turns Chuck Berry's classic into something completely new.
Fox, learned to hand dub the actions. It looked so real that many fans still believe he played it live.
It's this scene in the movie that the audience relaxes and enjoys what this movie is, fun.
It's really magically for lack of a better word. It's the 80's coming to the 50's. Especially when Marvin Berry calls his cousin Chuck Berry to show him a new sound.
That's just good entertainment.
Stay tuned for more.
