Endgame: Russos Share Cap and Tony's Last Days on Set, Captain Marvel's First

In honor of the blockbuster's one year anniversary, directors Joe and Anthony Russo did a tweet-along of Avengers: Endgame on Monday as part of ComicBook.com's Quarantine Watch Party. While the filmmakers didn't reveal much in the way of news -- honestly, what more can they say about the Marvel epic that they haven't already said? -- they did post a series of sweet behind-the-scenes photos and brief videos showcasing the cast and locations. Endgame screenwriters Christopher Markus and Stephen McFeely also tweeted along, while none other than Tony Stark himself, actor Robert Downey Jr., joined Joe Russo on his Instagram Live segment. Check out the highlights of their Endgame behind-the-scenes posts and anecdotes below, from Brie Larson's first day ever playing Captain Marvel to Chris Evans' last day playing Captain America and Robert Downey Jr. after filming Tony's "I am Iron Man" snap:

This was @brielarson’s first day ever as Captain Marvel… And here’s a quick video of her greeting the cast for the first time. #AvengersAssemble pic.twitter.com/ewMLDqgVGk

This is from @ChrisEvans’s last day of playing Captain America, ever. Much love and respect to you sir. What an amazing run. #AvengersAssemble pic.twitter.com/LreTlM2JrZ

Downey’s last day on set after shooting the “I am Iron Man” moment. The very definition of a legend. We love this man 3000. @RobertDowneyJr #AvengersAssemble pic.twitter.com/wIiQ5AwsDJ

The Russos also revealed some tidbits about Cap throughout the tweet-along:

It was early in development when we let him know he was going to pick up the hammer… needless to say he was psyched. The crew on these films are filled with comic book lovers, so you can guess how excited everyone was the day we filmed this. #AvengersAssemble https://t.co/X2uJl5vohN

Early on in development talks we considered making Cap the soul stone... But that idea fell away rather quickly. #AvengersAssemble https://t.co/admPgFOM3c

That long crane shot to find Cap and Peggy in the window... our favorite shot in the movie. #AvengersAssemble

The filmmakers posted several on-location photos and videos of scenes featuring Thor and Rocket's visit to Asgard to Ant-Man, Hulk, Cap, and Iron Man in New York:

Here we are working with our cousin Rene Russo. Jk. She’s not our cousin, she’s our sister! #AvengersAssemble pic.twitter.com/44DOz7UDVB

Rebuilding a set from a pre-existing movie is pretty damn cool. Also getting to hang out with the same, amazing cast year after year is also pretty damn cool… #AvengersAssemble pic.twitter.com/az1m65p68O

Hemsworth was not thrilled with Steve's writing in this particular scene... -CM #AvengersAssemble #QuarantineWatchParty pic.twitter.com/eoOhVqgY4l

Our insanely talented crew transformed a street in Downtown ATL into Tokyo for this Oner…#AvengersAssemble pic.twitter.com/RoCOoBtEgX

The Russos also paid tribute to the late Stan Lee, who shot a cameo as a hippie during the film's 1970 time heist sequence, as well as to Robert Redford, who reprised his Winter Soldier role as SHIELD's Alexander Pierce:

A monumental day. And that Steppenwolf song was in the script from the first draft. -CM #AvengersAssemble #QuarantineWatchParty pic.twitter.com/cCIqNzleGj

Nothing can accurately describe the overwhelming sense of awe you get when working with Robert Redford. The first time Joe’s daughter Ava (at 8 years old) met Robert, she ran up to him and said, “You’re that guy from the Sting movie!” #AvengersAssemble pic.twitter.com/RtbdwNoifD
