Warner Bros. has acquired the script “World Breaker,” co-written by Will Eubank and Philip Gawthorne, which Eubank will direct.

Brian Kavanaugh-Jones, Ben Pugh and Rory Aitken are producing. Joseph Vicenti and Joshua Horsfield executive producing.

Story follows a mythical Scottish warlord and his sons who withstand a massive castle siege launched by the ruthless commander of an invading army.

Drew Crevello and Julia Spiro are overseeing for the studio.

Warners is already high on the medieval-themed projects as it is in pre-production on the Guy Ritchie King Arthur pic “Knights of the Round Table.”

This is the second project with Warners for Eubank, who will direct “Tautona” from a script he is writing with Carlyle Eubank and David Frigerio, with Lorenzo Di Bonaventura and Mark Vahradian and Kavanaugh-Jones producing. Eubank most recently directed the sci-fi thriller “The Signal,” for Focus, which he also co-wrote, which premiered at Sundance this year.

Eubank’s profile among studios is rising following critical acclaim for “The Signal” at the festival.
