Actor Chris Pratt, who plays the leader of the “Guardians of the Galaxy,” confirmed that he filmed some scenes with Robert Downey Jr., who portrays Tony Stark.

Pratt described filming with the latter as “incredible,” during an interview with Entertainment Weekly. “It seemed like a dream, as so much of these past few years has felt, like a weird fever dream where you’re waking up and you’re not sure if you’re hallucinating or not,” he continued.

He also described Downey as “natural” and a remarkable actor.

“I’d heard stories about his work ethic, and his specific style of acting in regard to being in the moment, changing things up, keeping you on your toes,” Pratt asserted.

The third sequel of “The Avengers” follows the aftermath of the events that happened in the third “Captain America” film. In “Civil War,” Iron Man turned his back from Steve Rogers (Chris Evans). He did so after the latter defended the man who killed Stark’s parents, the Winter Soldier (Sebastian Stan).

As the leaders go their separate ways, the Guardians join Capt. America’s (Chris Evans) team for one common cause — fight Thanos and keep all Infinity Stones away from his cruel intentions.

During the casting of Quill for the first “Guardians of the Galaxy” movie, Pratt stated that director James Gunn was looking for someone who could work well with Downey’s character in the upcoming Marvel films.

“He knew that character had that potential, that there was a collision course for these characters, potentially,” Pratt explained. Since then, the actor has tried his best to perfect his portrayal.

In his February interview, executive producer Kevin Feige hinted that the upcoming movie will combine the entire Marvel Cinematic Universe. He went on to say that Thanos is the most powerful nemesis, and “The Avengers” are unprepared to face him.

“Avengers: Infinity War” will premiere in theaters on May 4, 2018.
