Carrey has hidden behind invented faces before, in " The Mask ," for example, but his Grinch, with his pig-snout nose and Mr. Hyde hairdo, looks more like a perverse wolfman than the hero of a comedy.
His off-the-wall performance is reminiscent of what he accomplished in The Mask, except that here he never allows the special effects to upstage him.
While the Grinch himself is padded, furry, and caked with even more green paste than he wore in The Mask, the Whos are almost frightening in their appearance, with their faces pinched forward and their noses built up like that of holiday-bedecked rodents.
His voice, a cross between Sean Connery and The Mask character was absolute perfection for Sir Grinch.
The comedic actor seems the virtual perfect match for this role, just as he was the perfect choice for the title character in The Mask.
