Talking loud and saying nothing

Every time Jack McCall (Eddie Murphy) says a word, a leaf falls from his garden tree. And when there's no leaves to fall, he dies. There are 1,000 leaves in the tree, so if he must speak he has to use the words wisely. A far-fetched and ludicrous story, a comedy that too desperately tries to be funny and without a proper household name and an expert for physical and verbal comedy for a leading role, the movie would be - quite honestly - qualityless.
