The Latin Grammy nominated song "Despacito" is a smash hit on YouTube. But if you ask Google's personal assistant to play "Despacito" it can't understand the command. Even though YouTube is part of Google. It's a learning moment about artificial intelligence, how natural language processing works and why machines still struggle with translation and foreign accents.

Over the course of his career, the filmmaker has put his unique stamp on everything from vampires ("Cronos") to superheroes ("Hellboy") to giant robots ("Pacific Rim") to gothic horror ("Crimson Peak"). The just-released first trailer for del Toro's latest film, "The Shape of Water," finds him back in the realm of dark, unsettling fairy tales, a la his 2006 film, "Pan's Labyrinth" -- this time with a suitably twisted romantic spin. Set against the backdrop of the Cold War, the film centers on a mute janitor (Sally Hawkins) at a top-secret government laboratory who develops a relationship with an aquatic humanoid creature (Doug Jones) -- the last of his species -- who is being held in a tank and subjected to experiments. "The Shape of Water," which co-stars Octavia Spencer, Michael Shannon and Richard Jenkins, hits theaters Dec. 8.
