It leaves him little room to differentiate himself from the parts he plays (rememberall the bizarre tales of his transmogrifying into Andy Kauffman on the set of Man on the Moon), or converselyto differentiate the parts he plays from the way he wishes to be seen. And he wishes to be seen as someone whonever gives offense, is impossible not to like. Which leads inevitably enough to Opie Howard's shining,saccharine Grinch and the even greater depths of The Majestic, the execrable little post-WWII fable that'sbeing released to home video this month. They call it "Capra-esque," but Capra never made anythingthis treacly. Carrey does everything but lick the camera to pull you nearer, but it's a con. You know thereare plenty of things he's too afraid to show you. Even the Academy Award nominators, usually suckers forsimpering flattery, were repelled this time. But no matter. "Carrey has never been better," ravedRoger Ebert. The show must go on.
