They probably do act well in films they dont produce themselves but the films they make are rubbish.
Think its Damon and Marlon.
Martin Lawrence is hit and miss Big mommas house is cak but a film he did years ago where he kidknapps some fella who is p!ssed off was funny, as was Bad Boys.
And Stoney you mention one of them is talented in one program, think of the crapola films they have made, just not funny.
Crapola, that reminds me, School of Rock



Oh and Cable Guy and Liar Liar and Me, myself and Irene (Most underratedCarrey film, i reckon)
