WARNING: The following article contains spoilers for Avengers: Endgame. In theaters now.

The scale of the Marvel Cinematic Universe is completely unprecedented. No one could have imagined that it would become the cinematic behemoth that it is today back when it started with -- among other creative minds and talents -- Robert Downey Jr. and his critically acclaimed portrayal of Tony Stark in 2008's Iron Man (directed by Jon Favreau). Downey Jr. charmed audiences with his performance and brought Iron Man into the mainstream. It's fitting that the four-film Avengers arc would end with him.

Since the release of Avengers: Endgame, the stars of the ensemble film have posted videos taken from their last few days on set. Robert Downey Jr. has now shared his own video, which was taken after filming for his last scene had wrapped. We see Downey Jr. addressing cast and crew, thanking them for their work and acknowledging the many emotions he and everyone else felt, but rushing to goodbyes, saying, "I'm going to take Chris' lead, I'm going to save them for Instagram."

The actor was referring to Chris Evans' farewell to everyone involved in his career as Captain America, which the star posted to Twitter. The message, which the actor tweeted in October 2018, caused fans to speculate about Cap's fate in Endgame. To avoid spoiling the plot of the film, Evans, along with directors Joe and Anthony Russo, responded with unsurprisingly vague comments alluding to potential future appearances by Evans after Endgame.
