Obviously part 1 was filmed by itself, but part 2 and 3 of Back to the Future was filmed back to back. But they were pretty much guaranteed success as they were already based on an immensely popular film. I'm sure the film companies and production team would have to be 100% certain that the films and sequels would be rock solid at the box office. Peter Jackson must have been a great salesman and had a very receptive audience at New Line to get Lord of the Rings greenlit.
