Una vez en la vida

To date, Cronenberg's deepest film.

Jeremy Irons summons a performance of profound complexity, to pull off a double-act so credible that your feelings are divided, twin egg-like, between two characters. The polar-opposite attraction/repulsion of each brother's personality shines through in his every scene - to flesh out two characters so distant yet so deeply intimate, and do it so convincingly, requires more than acting, and this is by far his finest moment.

I can't say any more about this film other than that seeing it is a life-enhancing experience. Anyone who has ever taken potent substances with a close friend, as a kind of emotional rite, will be moved beyond words by the twins' climactic scene.

Never mind the detractors who say it's cold and clinical and abusive - they just don't understand it. There is love, warmth and beauty in abundance in this film - a horror film? A psychological thriller? A love story? Don't try and give it a name and place, it's just an essential part of understanding us: as adults; as children; as weird, fathomless organisms.
