Thriller novelist Karin Slaughter inked a deal with Amber Entertainment to adapt her Martin Misunderstood novella into a film. The company has struck an “exclusive release” arrangement with the grocery and retail company Tesco.

The novella has only been released in the US as an audiobook, but the paperback has sold more than a million paperback copies in Holland and hundreds of thousands of copies in the UK and Germany.

Here’s more about the film’s unique distribution deal, from the release: “Martin Misunderstood will be part of an innovative and perhaps paradigm shifting deal with the European retail giant Tesco, the 2nd most profitable retailer in the world. The film will have an exclusive release through Tesco and will then be distributed throughout the rest of the territories.”
