LONDON — Pedro Almodovar is planning to direct a sci-fi movie, inspired by his love of 1950s pics like “Invasion of the Body Snatchers.”“I am still young enough to make a science fiction movie. I have ideas for this genre,” the Spanish helmer said Sunday. “The way I would like to do it is present something impossible in a real, domestic way. One of the scripts on my desk is of that genre, so I hope to make that.” He admitted he didn’t know how soon that would be. “I live with my stories for many years. I write more like a novelist than a screenwriter,” he said. Almodovar was speaking at BAFTA in London, where he delivered the annual David Lean Lecture, in which leading filmmakers discuss the influences on their career. His lecture included clips from John Cassavetes’ “Opening Night,” Ingmar Bergman’s “Autumn Sonata” and Jack Arnold’s “The Incredible Shrinking Man,” juxtaposed with clips from his own work. Almodovar also paid tribute to his brother and long-time collaborator Agustin. The director was belatedly presented with his BAFTA award for a film not in the English language for “The Skin I Live In,” which is also a sci-fi movie of sorts. Almodovar won the award in February, but was unable to collect it as he was on location with his new film, “I’m So Excited,” which is now in post. Almodovar joked that he hadn’t worried about attending the ceremony this year as he thought he wouldn’t win having received four previous BAFTA awards (for “All About My Mother” and “Talk to Her”). “Since the beginning, the BAFTAs were extremely generous to me and my work,” he said. He recalled his best helmer win for “All About My Mother” beating Sam Mendes for “American Beauty.” “I will never forget Sam’s face when they said ‘And the winner is Pedro Almodovar.” The helmer reflected it had been his first best helmer award outside Spain. The lecture was delivered in English and Spanish with the help of a translator.
