Recalling the movie studios in his days of making B-movies, Ronald Reagan said, "They didn't want it good. They wanted it Thursday."
Although the studios made a lot of stinkers in those days - unlike today when every film is well-crafted, intellectually deep, and uplifting to the spirit - they made a lot of good and even great ones. The sad truth is if they'd taken more time and had more money, there is no guarantee that the films would have improved.
I served on a committee once where a very wise executive summed up one of the group's advantages. "We don't have a lot of money," he observed, "and that's good. If we had a big budget, we push funds here and there and would wander off into things that might be nice but aren't really needed. We'd also be less creative."
As it turned out, he was absolutely correct. The restricted funds and the tight schedule, to steal a line from Samuel Johnson, concentrated our minds wonderfully.
