"Producer" is used lightly for him. Pretty much the guy gets money for stuff, probably securing a portion of the overall budget, and they throw him a bone by giving him a no-show, do-nothing credit.
This. I suspect he hasn't even seen most of the films he 'produces'. He does slate financing which means these films as just numbers on a spread sheet to him.
His producer credit is a contractual thing hence why he doesn't get the "pga" tag after his name.
Also, I have never net this man but his wife/fiancee/whatever is a fucking nightmare. Urgh. That is all.
