While on the set of 2019's biggest movies, Chris Pratt whipped out his phone and took a very illegal video of his co-stars.

*Potential 'Avengers: Endgame' spoilers ahead*

If you haven't seen 'Avengers: Endgame' yet, and don't want to know ANYTHING about the Marvel movie, then do not continue to read (and please, go to see the movie).

Chris Pratt, who plays Starlord in 'Guardians of the Galaxy', and who turned into dust at the end of 'Avengers: Infinity War' just uploaded a very spoiler-ific video to his personal Instagram page. Presumedly a scene from the final battle, the amount of stars he captures in the short clip is mind-boggling.

Have a look at the video below, and see how many Avengers you can spot.

From the video, we can see nearly every heavy hitter from the Avengers somewhere on set - and boy, do they love to wear baseball caps. First, there's Dave Bautista in full Drax make-up; next is Don Cheadle and Elizabeth Olsen without her Scarlet Witch wig; followed by the stunt doubles for Karen Gillan's Nebula and Zoe Saldana's Gamora; then, we see Chris Evans in conversation with Paul Rudd and a mystery man with his back to camera; Jeremy Renner, Chris Hemsworth, and Sebastian Stan are looking thoughtful in the background; Chadwick Boseman chilling on his own; Mark Ruffalo talking to a mystery brunette, while Mantis actress Pom Klementieff walks in front of shot; Tom Holland and Robert Downey Jr. discussing a scene; Danai Gurira is also in a conversation with (potentially?) Tessa Thompson; and then Benedict Cumberbatch's stunt double waits in the background also.

Finally, we get a shot of actor Sean Gunn who jokingly says "I'm pretty sure I'm the most famous person here", before Chris Pratt turns the camera on himself saying he's recording "a really illegal video." And then of course Chris Evans comes up to playfully whack Pratt, saying "Big time."
