I’ll go first. Mine is the instant knockout drug. Like Dexter’s intramuscular injection that causes someone to immediately lose consciousness. Or in the movie Split where there’s the aerosol spray in your face that makes you instantly unconscious. Or pretty much any time someone uses chloroform.
I mean with the complexity of shooting in a moving car I have to wonder if it’s ever done now.
All they need to do to solve the problem is make sure to focus on the road. They don’t need to actually be driving, just act like they are driving by looking at the road more than their passenger.
Well that’s to solve the appearance, but I’m commenting with an actual physical car, on a closed road, being towed or not, etc. Don’t need the bother when you can green screen it.
Filmed in a real setting always looks less distracting than a green screen.
On any union tv show or movie in the United States, all driving sequences are either in a studio shot with a green screen or a virtual stage, or they are shot with a “process trailer” where somebody else pulls the car.
It is very much illegal to have an actor “act” while driving, though in the low budget indie world you might find productions or cast willing to risk it in some way.
Indie movies and small budget movies, perhaps?
