Guardians of the Galaxy looks awesome. It stars loads of our favourite sci-fi actors in places where you wouldn't necessarily recognise them. One of those invisible favourites is Bradley Cooper as the voice of Rocket. Here's a quick screen test of his character, and a listen at how he sounds in the role.
From the sounds of things in this short clip, Rocket's hobbies include snarling, firing oversized weapons and inciting prison riots.
Check out the full trailer for Guardians Of The Galaxy below for more Rocket action.
The film premieres in the US on August 1.
