The rather prolific of late Bruce Willis is set to grumble and frown his way through a new action thriller entitled Fortress.

Did we say “action thriller”? Sorry, we meant “action cyber-thriller”. Here’s the brief: “In this dazzling action cyber-thriller, Bruce Willis (Pulp Fiction) plays Robert, a retired CIA agent living at a secret resort in the woods. One day, his estranged son drives to the camp for a visit — but he’s followed by Robert’s old nemesis, Balzary (Chad Michael Murray, TV’s One Tree Hill). As the site is besieged by Balzary’s attack squad, father and son retreat to a high-tech bunker. But are its steel walls and advanced weapons powerful enough to match Balzary’s bloodthirsty plans for revenge?

So, it’s kind of Panic Room on steroids then?

Anyway, Fortress is set for release in the US on December 17. Take a look:
