"I remember being blown away in this moment on the Avengers set. Nobody was allowed to film anything on their phones. I said screw it. No rule was going to stop me from seizing this once in a lifetime opportunity to capture this collection of stars, a group that likely will never be in the same room again," Pratt captioned his Instagram post. "We are so blessed."

"This is a really illegal video," Pratt said to the camera before Evans came into the shot to let him know he'd be in "big trouble."
