Rocket Raccoon's "Space dogs" Line in 'Infinity War' Came From A Kid At A Test Screening

Sometimes great suggestions can come from surprising places, and that goes for Marvel's Avengers: Infinity War too.

It turns out one of Rocket Raccoon's best lines actually owes its origin to a child at a test screening, something the team behind Infinity War revealed during the Blu-ray/DVD commentary. Directors Anthony and Joe Russo along with screenwriters Stephen McFeely and Christopher Markus watched the scene where the Outriders are making their way through Wakanda's force field and revealed where Rocket's space dogs line came from.

McFeely said: "Here come the Space Outriders", with Markus adding "The hounds." Anthony then alluded to the line's origin, saying "You never told the space dog story before."

"What's the Space Dog story?' McFeely asked.

"Well, there was a focus group after one of the test screenings," Anthony Russo said. "Somebody was commenting on something that happened in this section of the film, and he said, "You know those space dogs?" He referred to them as space dogs."

"So he thought it was hilarious, so he incorporated it into Bradly Cooper's read," Joe Russo said.

Anthony was pretty proud of that, saying "Now, Rocket refers to them as space dogs when he's shooting at them. He's like "Come on, space dogs!"

Just goes to show you never know where inspiration is going to come from.
