Back to the Future as period piece May 23 2011
Theory: Robert Zemeckis intentionally made Back to the Future not as a contemporary film set in the present but as a period piece set in 1985.
Back To The Future is both undeniably timeless (its place in pop culture is beyond question) and incredibly dated (it's very much a product of its time). Interestingly, it's a period piece made in 1985 that depicts 1985 as an era as distant-seeming as its version of 1955. Of course, when Back To The Future was first released, 1985 just looked like "now." It's entirely possible that director Robert Zemeckis and co-writer Bob Gale referenced Ronald Reagan and Eddie Van Halen and dressed Fox's Marty McFly up in a denim jacket and Calvin Klein underwear because they wanted Back To The Future to exist in the same universe as The Breakfast Club, Girls Just Want To Have Fun, and other teen films from 1985. But I'm going to give them way more credit than they probably deserve. I think Zemeckis and Gale knew all the timely accoutrements signifying "the present" in Back To The Future would inevitably look like 1985 within just a couple of years; in fact, they were banking on it. Zemeckis and Gale were trying to create an archetypical representation of 1985 just like they did for 1955, with its soda fountains, social repression, and subjugated black people. In this way, Back To The Future only gets better the further we get from the '80s. Everything that defines Marty McFly-how he walks, talks, acts, and dresses-acts as instantly recognizable shorthand for the year he comes from.
