A mental traveler, Stéphane (Bernal) spends his nights dreaming himself the host of a one-man television show, Stéphane TV. The set is a sort of shag-rugged, eggbox-baffled padded cell. Playing to a cardboard camera, Stéphane supplies his own musical accompaniment, interviews guests (mainly his mother), and invites the viewing audience to watch him "mixing up" his visions in a fake kitchen. In the waking life that he processes each night on his show, Stéphane has returned from Mexico, where he lived with his late father, to the family apartment in Paris. This splendidly regressive setting is another version of the dream studio Stéphane sleeping on a tiny bed surrounded by boyhood knickknacks and Rube Goldberg gadgets.
Stéphane's mother (Miou-Miou), who lives with a sour stage magician, gets her son a job at a print shop. The boss is not impressed with Stéphane's idea for a calendar in which each month is identified with a celebrated disaster. But like every other place where Gondry's over-imaginative hero finds himself, it's staffed with weirdos and rich with material to be hallucinated on his show. Stéphane's life becomes further complicated when Stéphanie (Charlotte Gainsbourg) moves in across the hall. Stéphane is not exactly attracted to her. She's thin, with delicate, bony features and impossibly prickly. But the absence of attraction is no barrier to obsession.
Stéphane and Stéphanie have more in common than their complementary names. Both are childish, albeit in differing ways, and involved in manufacturing and collecting little fetishes. They are, in the deepest sense, soul mates as Stéphanie belatedly realizes after Stéphane reconfigures her prized toy horse for actual movement. Stéphane is an artist who (like Gondry) works from household materials. The frantic idyll, once the couple begins collaborating, suggests a kindergarten crafts project run amok. The rest is more like Romper Room Resnais or a cross between David Cronenberg's Spider and Pee-wee's Playhouse.
Objects have a life of their own. (One morning Stéphane wakes up with his feet in the refrigerator.) Indeed, The Science of Sleep is basically a magpie's heap the clutter of wacky non sequiturs littered with throwaway gags and festooned with Freudian slips. Gondry's off-kilter visuals and hieroglyphic mise-en-scène are underscored by the protagonists' accented English individual words are made strange. Gondry is a far sunnier surrealist than Jan Svankmajer, but The Science of Sleep is not all that different from the season's other exercise in object animation, the Czech maestro's Lunacy: In each, the animated world mirrors the protagonist's tumultuous inner life.
Cross-cutting between Stéphane's dreams and reality, reprising material in a variety of different contexts, The Science of Sleep is an extraordinarily playful movie. The mood is borderline fey. But no less than its hero, the movie is too strange and even infantile to be whimsical. Stéphane fantasizes adult success and suffers from unrequited love. His loneliness is everywhere apparent: "I wish I could talk with my dad," he says mournfully. The final fantasy of Stéphane and Stéphanie riding off together on what might be Gumby's horse across a crumpled cellophane sea is less apt to warm your heart than break it.
