It’s a featurette on casting Anakin.
I have no idea why I wasted my time watching this, but when Lucas was talking to all 3 actors at the table, JL was seated in the middle and he was the only kid George looked at when he spoke.
The other two child actors were even worse than JL. The only conclusion I can draw is that the 3,000 kids thing is a pathological lie, especially given the things Lucas said in other interviews.
