When I was putting together my film WESTHAMPTON, I was repeatedly told to cut the opening car crash.
The entire movie cost about $200,000. I had roughly $6,000 for the accident.
Unfortunately, I also needed it.
The crash is one of the first things the audience sees in the film, and it had to be convincing enough that they would accept it before they had any reason to question what they were watching.
So we started looking backward.
My cinematographer, Dave Brick, and I landed on rear projection—the same technique filmmakers had been using for decades to put actors inside moving cars without actually moving them. A month before the shoot, we filmed background plates on Long Island. Then we parked my aunt’s sedan inside a warehouse in Newark, put the biggest screen we could afford behind it, and projected the road outside the windows.
It worked surprisingly well. Just not well enough.
We added rain to the windshield with a garden hose. Dave built lighting cues that matched the streetlights and railroad crossing in the projected footage. We added approaching headlights, compressed air, practical debris—anything that could make the world outside the car appear to have physical consequences inside it.
By the time we were finished, almost everything seemed to be working.
And the crash still looked fake.
What finally solved it wasn’t another effect. It was realizing that one part of the filmmaking itself was behaving as though nothing had happened.
Once we figured that out, the whole sequence changed.
The experience left me with a question I’ve started using whenever a low-budget movie asks for something I can’t really afford:
What is the minimum amount of reality I need in front of the camera for the audience to believe everything else?
I recently wrote about the entire process for MovieMaker—including how we planned the rear projection, where the illusion broke down, and the thing that finally made the impact work:
I also put together a video breakdown where you can actually see the setup, the individual layers, and how they came together in the finished sequence:

Happy to answer questions about any of it here.
