With all of the movies that have led up to Avengers: Endgame, there's been ample opportunity for the MCU stars to get to know each other over the years. And fortunately, many of the Avengers actors are friends in real life — as proven by how chummy they have become during their many interviews to promote the many Marvel movies that have been released. It's impossible not to feel joy while watching, say, the three MCU Chrises goof off together, or to see Anthony Mackie and Sebastian Stan talk about the escape room they visited before hitting a red carpet.

Plus, a number of the Avengers actors have worked together before joining the MCU, too. Did you know, for instance, that Tom Hiddleston and Benedict Cumberbatch's friendship goes all the way back to 2011's War Horse? Or that Winston Duke and Lupita Nyong'o went to Yale together?

Here are some of the best star-powered friendships to come out of the MCU, along with photos to prove just how close the actors are. No matter what happens at the end of Avengers: Endgame, the movie's stars have found lifelong friends in each other during the years of filming the Avengers movies. And that's something special in its own right.

The two Chrises were paired together during Avengers: Age of Ultron press interviews in 2015, and they couldn't stop making each other crack up. Oh, and Chris Evans called Chris Hemsworth "Hemmy" during a recent interview.

2. Brie Larson & Samuel L. Jackson

Before Captain Marvel, Larson and Jackson co-starred in Unicorn Store and Kong: Skull Island, both of which premiered in 2017. And according to Vulture, it was Larson's idea to have Jackson's Nick Fury play a bigger role in Captain Marvel. The best evidence of this friendship, though, might be the duo's performances of "Shallow" and "7 Rings," which are both quite fun to watch.

3. Robert Downey Jr. & Mark Ruffalo

If RDJ let Ruffalo try on his sunglasses (click through to the third slide), you know this friendship is real. And in 2014, Ruffalo compared Downey, Jr. to an "older brother." There's also the time that Downey Jr., Ruffalo, Chris Evans, and Chris Hemsworth sang "Hey Jude" together, which is a delightful treat.

4. Tom Holland, Robert Downey Jr., & Chris Evans

Downey Jr.'s Instagram post is cute, but it's Holland's comment that really makes it. Holland wrote, "the love is real boss man." Seeing him call the actor "boss man" is really just too good.

5. Paul Rudd & Jeremy Renner

For Rudd's birthday earlier this month, he and Renner posed for a hilarious photo making fun of The 40-Year-Old Virgin, which Rudd acted in. And for Rudd's birthday earlier this month, One reporter even nicknamed their relationship "Rudder," so it's really official now.

Hemsworth and Rudd seem to have had a mini prank war going on behind-the-scenes. Apparently, the Thor star drew all over an Ant-Man poster, but it's not clear if Rudd got his costar back in the end. The faces they're making in this picture, though, are a reminder that it's all in good fun.

7. Brie Larson & Robert Downey, Jr.

As Screenrant explained, the MCU wasn't the first time these two acted together. Johansson and Evans starred in The Perfect Score in 2004, long before they were Black Widow and Captain America. They also co-starred in The Nanny Diaries in 2007. These days, they make faces at each other on Avengers red carpets.

17. Chris Pratt & Tom Hiddleston

Hiddleston looks like he's having a little more fun in this picture, but Pratt's caption emphasized how much he enjoyed his costar's company. "Hanging on the carpet with the god of mischief himself @twhiddleston helluuva nice guy and great actor," Pratt wrote in April 2018.

18. Letitia Wright, Lupita Nyong'o, & Danai Gurira

Black Panther stars Wright, Nyong'o, and Gurira are just as close off-screen as they were in the movie. And Daniel Kaluuya's photobomb really makes this the perfect picture.

The Captain America: Civil War costars' offscreen friendship has been well-documented by fans on YouTube. Please cut to 1:47 in this video, where the actors talk about the pocket square Stan gave Mackie for Christmas, featuring an image of his face.

"The power that that has. The intelligence that that has. The clearance that that has. The access that that has. The influence that that has. The profile that that has. The international implications that that has." Ana Navarro was speaking about Michael Flynn and the Russia investigation when she said this heavily memed statement on The View. But she could have also been talking about the fact that actors from Captain America: The Winter Soldier, Iron Man 3, Ant-Man and the Wasp, and Black Panther were all hanging out together.

Avengers: Endgame might signal the end for some fan-favorite MCU characters. But fans will always have plenty of photos and videos from the press tours to look back on, and it really does look like the actors will be friends for years to come.
