I'm not lying in the slightest. You don't count movies he directed himself, bit parts or movies nobody's ever heard of.

Ah, so we're just making up rules now, cool. Also, even with your criteria it still doesn't hold up. He directed none of those fifteen movies. All have Mel's name and image prominently on the cover...except the movie you're talking about. Literally. The one film you picked to focus on focuses the least on Mel Gibson.

And, I don't follow movies closely, but Fatman and Boss Level both seemed relatively big and mainstream. Professor and the Madman, too, I believe.

So you're once again incredibly off base.
