Marc Malkin Senior Film Awards, Events & Lifestyle EditorChris Pratt strips down to his underwear for an epic fight scene in his new Amazon Prime Video action thriller series “The Terminal List.”The scene finds the actor being attacked by would-be assassins while he’s undergoing an MRI.“I used to fight my brother a lot in my underwear,” Pratt joked at the series premiere in Los Angeles. “Oftentimes, we’d run around in our underwear fighting each other.”Obviously, “The Terminal List” fisticuffs were something quite different. “It was originally choreographed to be a little bit more like a big action fight sequence,” Pratt said.
