40 Unforgivable Movie Bloopers

Back to the Future

Historians really need to talk to film agents and get themselves work in the movies because there’s a lot of demand; they’re just not marketing their services well enough. In Back to the Future, Marty McFly hits the stages and shows off his guitar skills, shocking everyone in 1955 to his rock riffs. Unfortunately, the guitar he plays, a Gibson ES, doesn’t show up until 1958. This kind of detail is really objectionable when the premise of the movie is time travel.
