"Bring a bagged lunch," Robert Downey Jr. (Iron Man) joked, and Mark Ruffalo (The Hulk) added, "Bring a box of Kleenex and a diaper."
Jokes about the length aside, the cast says the film holds a special place because it's the culmination of more than a decade of work.
"It is the end of a 22, 21-movie tapestry," said Chris Evans, who has hinted that this will be his last movie playing Captain America. "When you think about it, it's easy to get emotional."

"Even if there's a small chance that we can undo this, we owe it to everyone who's not in this room to try," Black Widow (Scarlett Johansson) says.
"If we do this," Bruce Banner/the Hulk replies, "how do we know it's going to end any differently than it did before?"
Captain Marvel (Brie Larson) chimes in: "Because before you didn't have me."
