Bradley Cooper On 'Guardians 2': 'I Do Whatever James Gunn Tells Me To Do'

But, really, what's a raccoon?

"Guardians of the Galaxy 2" is hotly anticipated here on earth and, we assume, on other planets throughout space as well. Bradley Cooper, who voiced Rocket Raccoon in the first installment of Marvel's budding space cowboy franchise, is among those looking forward to the sequel.

At a press day for "American Sniper," the Best Picture nominee that garnered Cooper his third Oscar acting nomination in as many years, Cooper told MTV News where he's at with the sequel.

"I don't know how it'll work, I just do whatever James Gunn tells me to do," Cooper said.

He even recited one of his most memorable lines, to the delight of "American Sniper" co-star Sienna Miller: "What's a raccoon?"

Beyond that, if you're hoping to get plot scoop from Cooper (WHO IS STAR-LORD'S DAD?), good luck.

"I don't know anything about it," he said. "Nothing."

"Guardians of the Galaxy 2" is set to hit theaters May 5, 2017.
