Leonardo DiCaprio will produce and star in an untitled action thriller focusing on the growing global phenomenon of mercenaries used by governments and companies to wage war according to Variety.

Scott Burns has been set to write the script which DiCaprio's Appian Wayt productions will produce. Leo apparently sparked to the idea of mixing a thriller element with the cautionary theme of outsourcing war. The idea was hatched by an NY Times Magazine foreign correspondent.

Burns wrote "The Informant," a fact-based thriller about a corporate whistleblower to star Matt Damon; Steven Soderbergh will helm the pic next spring. Burns also scripted and will direct "PU-239," a drama about black market plutonium in Russia.
