Donnie(Jake Gyllenhaal) is sleepwalking every night and seeing his imaginary friend Frank, with a snarling metal bunny mask and suit. The movie leaves you guessing whether or not what’s happening is just Donnie’s fantasies(a therapist calls his symptoms those of a paranoid schizophrenic). He meets a girl(Jena Malone) who he starts going with. A book on time travel mirrors Donnie’s delusions. The picture floats and hums, it could be seen as frightening were it not for the humour that courses through parts of it. Like Donnie, the picture smirks and slips and cries. The ending is not a happy one.
