Movie after movie finds Carrey either confronting God (“Smite me, O mighty Smiter!” he roars in Bruce Almighty) or enacting, violently and outrageously, some version of the dilemma identified by the Spanish existentialist José Ortega y Gasset—that man, as he exists in the world, is “equivalent to an actor bidden to represent the personage which is his real I.” One wonders what the French make of him. Here in America, we’ve been content to regard him as a blockbustering goofball, but in France, beautiful France, where philosophy is king and Jerry Lewis is awarded the Légion d’Honneur, might not they be readying garlands for Jim Carrey?

Yes Man, out this month, is Carrey’s latest existential parable. If, as has been speculated, Hans Christian Andersen and Søren Kierkegaard shared a libertine moment in the salons and cellars of 19th-century Copenhagen, they could have brainstormed this movie over drinks. Carrey plays Carl Allen, an office drone and cautious Cuthbert who abruptly starts saying “Yes!” to everything—Korean lessons, cans of Red Bull, love, and life itself. This impulsive assent to existence is characteristically presented in the form of a gift/curse, laid upon Carrey, in this case, by a New Age positivity guru played by Terence Stamp. (The tie-in with Red Bull is a brilliant stroke, of course—no other legal product so generously extends the promise of turning you, if only for half an hour, into Jim Carrey.)

Leaping into lived truth also gets you the girl: Yes Man, like so many Carrey movies, trails off sappily into love. Really, though, where else could it go? To quote Martin Buber: “The world is not comprehensible, but it is embraceable.” The point is to commit yourself. Eternal Sunshine of the Spotless Mind imagines a pair of lovers, played by Carrey and Kate Winslet, in the heat-death of their togetherness: bored and disgusted, each submits to a disreputable clinical procedure in which the whole relationship is expunged from their memory banks. It works, but somehow, as freshly minted strangers, they meet again; they are drawn to each other; they begin to fall in love. Then the attempt at mutual erasure comes to light: they learn that they have been through all of this already. What to do? In an overlit, discolored hallway, they stare at each other, grim with foreknowledge—and decide to go for it all over again. How beautiful! Ghastly as they look under the fluorescent tubes, the lovers stand together in this instant on a scuffed little summit of human dignity: by embracing their situation (and each other), they have transcended it.

All of which would be the sheerest philosophical prattle if Jim Carrey didn’t so consistently, as a performer, embody these various propositions. Here, buzzing in his shoulder sockets, is the struggle for authenticity; there, warping his tongue, is the torment of becoming. At his most Carrey-esque, he is always trapped mid-metamorphosis, wrestling visibly with the sort of transformative inner pressure that in another context would produce a superhero—or a man-size cockroach. The Mask got it all wrong by making this explicit, by separating the character of Stanley Ipkiss, shat-upon bank clerk, from the green-headed, dance-floor-dominating pimp he became when he put on his magic mask. (Jim Carrey with makeup? And special effects? Jesus, what a waste!) The Farrelly brothers’ Me, Myself & Irene, on the other hand, got it exactly right. Charlie Baileygates, Rhode Island state trooper, cuckold, butt of the world, a 6-foot-2-inch walking punch line (like Truman Burbank), goes to confession. “There’s something bubbling up inside of me, Father,” he whispers fiercely, “and I’m afraid that someday … I’m gonna explode!” “Where does this rage come from, my son?” murmurs his confessor. “I don’t know,” Charlie says. “I’m probably just being paranoid here, but I get the feeling that the entire town is laughing at me behind my back.” The priest leans forward: “Charlie? That you?” When Charlie explodes, there are no gimmicks. A hissing sound, a distension of the jaw, and he has turned into somebody else: it happens, in other words, behind his eyes.
