Rocket Raccoons röst görs som vi alla vet av komedistjärnan Bradley Cooper (Baksmällan) men skådespelaren gestaltar inte den datoranimerade tvättbjörnen under själva inspelningen av Guardians of the Galaxy Vol 2, en roll som istället utförs av regissörens lillebrorsa Sean Gunn. Varför? James Gunn förklarar i en nygjord intervju-grej på Facebook:
"Sean Gunn is not a stand-in. He is a motion reference actor. That means we film everything Sean does on set as Rocket. We film it. I don't stop doing takes of him until we get the performance right and then we use that performance as a basis for much of Rocket's acting. And he does a fantastic job in that role. He knows it. He understands it. And also very important, Sean is able to physically do something most actors aren't able to do, which is waddle around on all fours. He's always been an incredibly limber guy that can to do a lot of strange physical things. And the fact that he's able to waddle around on his legs all day long at the exact height of Rocket is quite a feat and quite quite difficult."

Vad tycker du om Bradleys insats som rösten till den käftiga pungråttan?
