Why should movies get the science right?
I have long heard that some/many sci-fi movies get the science wrong and I just sit there thinking -"well what's wrong with that?".
I've managed construct a few bad reasons as to why they should get it right, but most of these are somewhere along the lines of: 'it might mislead people'. Your help will be much appreciated.
I don't think there's any general injunction about getting the science right, but sometimes getting it wrong can be a distraction. One example that's been discussed by various critics comes from Lord of the Flies . Piggy's glasses are used to focus sunlight and start a fire. But Piggy is nearsighted; his lenses would be concave rather than convex and couldn't be used to start a fire. (Thanks to John Holliday for this example, which he discusses in his dissertation.) Many readers won't realize the problem, but the glasses and Piggy's nearsightedness aren't just an incidental plot element. This is the sort of detail that Golding could have gotten right and once you know that it's wrong, you may never be able to read those scenes in the same way. Needless to say, this doesn't show that getting the science right always matters. It surely doesn't. It's also plausible that these things will be matters of degree. The more esoteric the bit of science, and the less central to the story, the less it's likely to...
