Jim Henson Co. has bought the rights to the fantasy adventure book, The Boggart by novelist Susan Cooper, The Doubtful Guest by Edward Gorey, and the fantasy adventure trilogy, Monster Blood Tattoo by D.M. Cornish.

Variety describes the books as:

The Boggart - originally published in 1993, centers on a family from Toronto inheriting a Scottish castle with a gleeful spirit who's been playing tricks on residents for generations. It's to be developed as a live action family feature with Brian Henson directing.

The Doubtful Guest - debuted in 1957, revolves around acreature that shows up at a family-owned bed & breakfast. It's the furthest along of the three projects with Brad Peyton ("Evelyn: The Cutest Evil Dead Girl") directing and Matthew Huffman penning the screenplay.

Monster Blood Tattoo - a series of three books, Foundling, Lamplighter and a third untitled novel, set in the world of the Half Continent, a magical Victorian realm where an orphaned boy embarks on a perilous quest to become an apprentice to a line of monster bounty hunters. No writer or director is attached; Henson Co. hasn't decided how many features it will adapt from the trilogy.

In other Henson Co. news, they're turning Fraggle Rock into a feature film; they've hired Ahmet Zappa to write a treatment for a pic about the underground denizens.
