The attractive Spanish actress Natalia Verbeke, very well dressed, has entered a beautiful house; she takes off her coat, climbs the stairs to the first floor, opens a door and, just as the soundtrack reaches the climax, she says: "I'm back! And I plan to come back every day of my life" A preview of Almodovar's new film? The umpteenth tribute to Hitchcock? The new perfume by Chanel? No, an amusing spot which shows very graphically how effective our fibre -enriched milk is."
