If that's what Rudin does, that seems like a pretty smart way to go about a risky business. As an investor, you're investing in the person (Rudin), not the particular project. So Rudin gets funding for not only the slam dunks (MOCKINGBIRD, DOLLY), but also his passion projects like GARY. And everyone is insulated against the flops by the hits.
So you're trusting Rudin's taste as a producer, just like subscribers to an institutional theatre trust the leadership of that company to produce material they are interested in seeing, even if you have to pay for your subscription before all the productions are announced. You either trust or you don't.
Now, if Rudin's track record starts to change and there's more GARYs than DOLLYs, then people will start to reconsider. But right now, I'd hand him my money...if I had any.
