Avengers: Endgame star Chris Pratt’s ‘illegal’ set video viewed 18m times on Instagram

'That's why you are Star-Lord'

Chris Pratt’s “highly illegal” video filmed on the set of Avengers: Endgame has now been viewed online just under 18 million times.

The actor, who plays Guardians of the Galaxy character Peter Quill, posted the clip – featuring an array of high-profile stars – on is Instagram page.

Featuring many of the film’s actors preparing to shoot one of the film’s biggest battle sequences, the video is deemed “really illegal” by a smiling Pratt.

Actors including Paul Rudd, Chris Evans, Elizabeth Olsen, Jeremy Renner and Chris Hemsworth can be seen in front of the green screen.

The video is itself a huge spoiler for the film’s events, considering it features many of the stars whose characters seemingly died at the hands of Thanos at the end of Infinity War.

Referencing the fact that Pratt is brandishing a banned phone, Captain America star Evans can be jokingly heard saying: “Big trouble, big time.”

Pratt's co-star Vin Diesel, who voices Groot, wrote underneath: "And that's why you are STAR-LORD!!"

The clip comes a week after the twist-filled full film found its way onto streaming sites after just 12 hours of release in China.
