Improvised nd filter?

Hello, I have an idea to photograph a moving subject that is in very bright light. I want to experiment with my 8mm Samyang lens. Problem is that it is impossible to get a filter that fits. I have read that it is possible to put a gel filter between the filter and the camera body. My question is would using a piece of black 35mm film act as an improvised ND filter or do I have to try and find a proper ND filter gel?
Any thoughts would be welcome.

Thanks

Mike
