Between Two Ferns, the genius 'Funny or Die' sketch starring Zach Galifianakis is back, and this time the actor is saying increasingly cold things to A-list movie star Brad Pitt.

On the promotional tour for his new WWII movie Fury, Pitt takes to the inter-fern seat like the seasoned pro he is, and his deadpan responses are up there with Obama's. 

Check out the sketch below, and hear an interview with Brad Pitt and co-star Shia LaBeouf on this week's The Green Room, with Orla Barry on Newstalk from 21.00.
