Are you a nitpicker? (saying it in a jesting tone)
When you read a Back-in-Time story, do time errors bother you? If so, you may want to hear what Michael J. Fox says in his memoir about one that he still gets complaints about in the movie "Back to the Future."
The error is in the iconic scene in which Fox's time-traveling teenager Marty McFly fills in for the injured guitarist in a 1955 prom band and launches into rocking renditions of "Earth Angel" and "Johnny B. Goode."
To play "Johnny B. Goode," Marty borrowed Chuck Berry's cousin's (Marvin Berry) Gibson ES-ยญ345, a guitar first introduced in 1958 -ยญ three years after the 1955 scene in the movie. Fox explains, calling the goofยญ "a temporal inconsistency that guitar aficionados and Back to the Future fans have pointed out again and again."
Guitar heads and Future devotees alike have taken note of the production flub, even pointing out that like the ES-345, Berry's "Johnny B. Goode" wouldn't be released until 1958. It would track that Marty knows the tune, coming from 1985, but how would his 1955 backing band know to accompany him on a song that wasn't yet written?
So do those time errors in the movie make the scene less great? Something to think about when reading a Back-in-Time story.
