I was going to suggest the magical spell to summon a person on the internet -- say their name three times in a high pagerank location with your eyes closed, of course -- but it only works for people who haven't yet tired of googling themselves.

In this case, the guy has 50 titles to his credit, some of them quite big blockbusters, so I suspect he's not going to notice. Maybe he'll have a nephew or other connection who'll let him know his input is urgently needed on a matter of great importance.
