One way or another, I watch a lot of old films, whether old TV shows, old movies, or even old instructional videos.
It’s informative, and not just in the way the original filmmakers intended. As C.S. Lewis pointed out, consuming work produced in a different time doesn’t just tell you what the work is about, but also how people thought and their basic assumptions about life. The point isn’t that it’s completely accurate to how life was back then, but that it does show what at least some people thought and felt at the time regarding the subject. It also gives a sense of how that subject might have been generally viewed by the audience, depending on the assumptions the creator felt he had to cater to.
For instance, viewing 1946’s Miracle on 34th Street, we can tell that having a woman in a position of authority in a major corporation like Macy’s Department Stores was not considered particularly unusual or surprising at the time it was made, since no one comments on or expresses surprise at Maureen O’Hara occupying such a position, and the film feels no need to provide any explanation for it. We can likewise gather that having a Black day servant was fairly normal for a well-off businesswoman, since again, the film feels no need to explain the character’s presence. On the other hand, the film does need to explain the difference between a hearing and a trial, because it’s not something the average audience member might be expected to know or take for granted, and they might become confused as to what the stakes are and the rules of the proceeding.
A steady exposure to the thoughts of many different ages is an indispensable defense against blindly following the zeitgeist and prejudices of one’s own particular age. Because what you get is actually what was said or filmed or thought at that time; not someone’s reconstruction of it.
For an example, consider the following short. It was intended for a proposed Mystery Science Theater 3000 tie-in CD that never got off the ground. Looking past Mike and Bots’ typical irreverent humor, we see an image of what Venezuela used to be like (sorry for the poor sound quality).
Now, obviously it’s a very positive portrayal, since the film is Creole Oil showing their employees how great it can be to work there, but look at what’s on screen; the clean, busy streets and beautiful buildings of Maracaibo and Caracas (many of them recently constructed, according to the film), the Sears store, the full car lots, the stores crammed with American products. This is, at least in part, what the country looked like in the 1950s, and how an American company interacted with the country.
