The Cabin in the Woods takes place (mostly) in America. The 20-something cast is in a big RV that has the driver's seat on the left. The ignition should be to the right of the steering wheel. However, at 10 seconds into the movie trailer, we see Chris Hemsworth turn on the ignition with his left hand.
Was this just included to make the audience subconsciously feel like something is "off"? Or is there a more mundane explanation, like this shot was flipped in the trailer or it's a special RV with the ignition to the left of the steering wheel?
Here's the trailer. This shot is 10 seconds into it.
