There's no money in movies anyway

I'm not sure there is any disadvantage to digital video taking over. The world is awash with video. Any bum off the street can make some kind of movie. Even if you make something good, the field is far more competitive now and your work may be lost in the flood of crap being made.

I've been reading Brian Albright's Regional Horror Films, 1958-1990, A state-by-state guide with interviews. I haven't gotten far into it yet, but the filmmakers don't seem to have made much money from their movies. Most made few movies, and I was just reading one interview with a filmmaker who lost all interest in the movie he once poured his life into. He could get it shown on TV with a little effort but it's not worth it to him. He's moved on.

I had written on here somewhere about Deluxe---if you looked at movie credits, it would often say "Color by Deluxe". Deluxe had a vault full of movies they were trying to give back to people, back to their owners. In a lot of cases, no one wanted them. The companies had gone out of business or the filmmakers had died, or the movie may have been such a bad experience that they just didn't want to see them again.

Filmmakers sometimes feel the same about their work as disappointed movie-goers. 

Think of how much less humiliating it would have been for everyone involved to have lost a thousand dollars instead of a couple of hundred thousand (millions today when you adjust for inflation).

You still have to figure out how to make it worth the trouble.
