Joel Silver knows a little bit about producing action-thrillers. With The Matrix and Die Hard in his repertoire and Sherlock Holmes: A Game of Shadows coming this December, Silver needs something new to work on. Enter The Envoy, a spec script picked up by Warner Bros. from writer Robert Lynn. Per Heat Vision, the plot revolves around a diplomatic courier who finds himself in possession of highly sensitive information. When he discovers those documents are stolen plans for attacks on American targets, he must seek sanctuary at the American embassy in Vienna. Of course, all manner of baddies are out to stop him along the way.

This is the first major sale for Lynn, who was a writer on HBO and Bravo’s Project Greenlight. He’s also written a number of low-budget thrillers, including Adrenaline, Prisoner and Deadbox. Sarah Meyer brought the script to Warner Bros. and will be a producer on the project. Along with Meyer and Silver, Andrew Rona, who teamed with Silver on Unknown, will also produce.
