The Sigma Protocol involves a young banker who stumbles upon a conspiracy to manipulate the world economy and finds himself an assassination target. Accompanied by a beautiful intelligence agent, he globe-hops to solve the mystery and elude his pursuers.
You may recall that Marcum and Holloway are also attached to write a Highlander remake. According to The Hollywood Reporter, they'll be doing The Sigma Protocol first. No director, cast, or timeline has been announced, but Sigma joins three other Ludlum projects in active development -- The Chancellor Manuscript, to star Leonardo DiCaprio, The Matarese Circle, with Denzel Washington attached, and a fourth Bourne flick with Matt Damon and director Paul Greengrass set to return.
The Bourne films are remarkable for making Ludlum's kind-of-silly (if entertaining) potboiler stories uncommonly classy, but I'd like to see one of these films embrace the silliness and really go over the top.
