Back in the late nineties a variation on this was for the scammer to call and say you'd be featured on some cable business show hosted by a big shot ex-politician. When they called me it was Casper Weinberger, but I remember hearing about other names too. The catch was that you had to pay the production costs of $15-25k.
This is also a common charity tactic. They throw a big dinner party honoring some rich guy, then shake down all his friends to pay for tables at dinner.
I've been there. We had a new person in the office who didn't believe that such scams could exist, so for the lulz they were assigned to deal with the person. They could say whatever they wanted as long as they didn't agree to pay.
The salesguy ended up screaming at our person who was just playing dumb.
We've had several of these companies approach our agriculture software company over the years. The key phrase to listen for is "scheduling fee" as that's what they call the $15k - $25k fee.
The most recent pitch was last year and the special host was to be Terry Bradshaw.
