Meet your art teacher today. It's Alan Snow, the man that wrote actually invented the boxtroll – in his book Here Be Monsters. This weekend the movie inspired by the book The Boxtrolls (created by the makers of Coraline) hits the screens in the UK, so what better time than to learn to draw one of these loveable trolls?Photograph: Alan SnowPhotograph: Alan SnowPhotograph: Alan SnowPhotograph: Alan SnowPhotograph: Alan SnowPhotograph: alan SnowPhotograph: Alan SnowWe couldn't resist sharing a couple of boxtroll movie stills with you. Alan Snow has found having a film made of his book Here Be Monsters an altogether strange experience: "seeing the characters and the world of the boxtrolls made solid by other artists is more than odd. It's like having a dream but knowing that there is a parallel universe outside of the dream which is slightly different."Photograph: PRFans of the film Coraline, based on Neil Gaiman's book of the same name, may notice some similarities in animation style to The Boxtrolls. There's a reason for that: The Boxtrolls is made by the same people – and they also made Paranorman. Find out more on The Boxtrolls movie website.
