Set in the US, the story revolves around three siblings who stumble across a "field guide to faeries" that opens up a parallel world. While the trio are discovering all kinds of benevolent little creatures, they come across some slightly less-friendly ones as well, and the latest poster even works in a little menace by adding 'Beware' to the heading. The family flick stars Sarah Bolger as Mallory Grace and Freddie Highmore as both Jared and Simon Grace. Rounding out the cast is David Strathairn as Arthur Spiderwick and Mary Louise Parker as Helen Grace.
There were over 12 books published as part of the series, including supplementary books, so there is a lot of material if Nickelodeon decides to make a franchise out of the film. Now that The Golden Compass' future is a little less sure, maybe Spiderwick can take the place of the "heir to Harry Potter" for children's fantasy films. The Spiderwick Chronicles opens on February 15th, 2008.
