Here's a different approach to a book ad/trailer, as reported in The Independent: "On Italian TV, The Female Labyrinth by A.L. Marra, a dull-sounding treatise on economics and banking, has had an unusual endorsement. It has been praised on camera by Karima El Mahroug, aka "Ruby the Heartstealer", the dancer in the Berlusconi trial. Ruby stands by a digital pack-shot of the book, wearing a red dress – but as she starts to speak, a Phantom of the Opera figure runs up and rips it off, leaving her to discuss the book's virtues in her bra and pants."
