Liman had previously been planning to work with Hardy in adventure movie Everest, based on the book Paths Of Glory, Everest by Jeffrey Archer, but the 2012 project failed to come to fruition.
The Splinter Cell movie has yet to receive a release date.
It's not the only Ubisoft game-turned-film heading to cinemas - Michael Fassbender will play the title character in an upcoming movie version of Assassin's Creed, which is expected to hit theatres next year (15).
