From an Interview with Mike Rubbo :
Rubbo: I have not met people [who are willing to live with the doubt and the mystery]. I have been travelling with the film and I cannot get the academics to come to my screenings. With one or two exceptions, they will not come. They don't want to engage in debate. Or if they do come -- I've also had public screenings in theaters, and I'm there after every screening to take questions -- they do not identify themselves. (...)It is a problem. To debate the authorship question, you have to study it. And for the Stratfordians this is both dangerous and a waste of time. To give it the time, of course, is to acknowledge that it has some worth. And to what end? What does it get them? The problem for them, and it's a real problem, is:
they won't end up with a new position.
