Introducing Keira Knightley's Jack Ryan Character Cathy

Jack Ryan: Shadow Recruit 's cast is about as all-star as you can get.

Flying the female flag amongst a testosterone heavy cast (Chris Pine, Kenneth Branagh, Kevin Costner) is our very own Keira Knightley, who plays Ryan's love interest Cathy.

But as our exclusive video featurette shows, it looks like she'll be far more important than beautiful window-dressing or a dreary damsel in distress.

Watch the star-studded video featurette below and let us know what you think in the comments below!

Jack Ryan: Shadow Recruit is in UK cinemas from 24 January 2014.
