Fans of darkly hilarious US show It's Always Sunny In Philadelphia and big screen comedies such as Horrible Bosses will be familiar with Day while British actor Gorman has made his face known thanks to roles in Game of Thrones, The Dark Knight Rises and Torchwood.

We spoke to the unlikely duo about UK vs US language differences, pretending to hate each other on-screen and their idea for Pacific Rim 2. It's a doozy.
