For Gibson, I loved his recent movie Get the Gringo. Really funny. Even does an imitation of Clint Eastwood directing a movie. Hilarious!
Re Gibson, The Imaginationland South Park episode has a scene where the military is trying to get help from Hollywood in conquering monsters coming from our collective imagination. They bring in several directors to help. First M Night Shyamalan, then Michael Bay and finally Mel Gibson.

I sort of like the first one the best. It was (to me) the closest thing to the original concept. Kept us guessing.
