We all know that even cult classics and widely beloved films are not immune to silly plot holes. However, this amusing moment, while not altering the storyline, quite literally fits into the film's atmosphere and aligns perfectly with its title.
This movie mistake in Back to the Future (1985) is related to the guitar played by the protagonist, Marty McFly.
An Easy-to-Miss Mistake
In the 1955 high school dance scene, Marty McFly performs Johnny B. Goode on a Gibson ES-345 guitar. However, there's a problem — this model wasn't released until 1958, three years after the events of the film.
How It Affects the Film
While this slip-up doesn’t alter the plot, it creates a paradox effect that ties into the theme of time travel. Marty brings elements of the future into the past, and though it happened by accident, one could humorously argue that his presence in 1955 'sped up' the invention of this guitar.
