Are you kidding? Even people who work there can't ask questions. The powers that be don't reveal info on this stuff to anyone.
No, I'm *not* kidding. It's a perfectly legitimate question to ask and considering how Universal felt compelled to acknowledge the impact on one of their releases, that means they *do* release info on this of some kind and if they were serious about trying to locate where other source elements might be, they might bother to be candid with the public on that point.
Who gave you your info on "Baretta" BTW if they don't reveal info on this stuff to "anyone"?
