We asked the BuzzFeed Community to tell us their favorite improvised and unscripted moments from Marvel movies. Here are the brilliant results.
In Avengers: Infinity War, Dave Bautista improvised the iconic "Why is Gamora?" bit.
In Black Panther, Michael B. Jordan ad-libbed the "hey, auntie" line when addressing Angela Bassett's character for the first time.
In Avengers: Age of Ultron, Robert Downey Jr. improvised the "please be a secret door, please be a secret door" line right before the secret door opened.
In Thor: The Dark World, Chris Hemsworth was playing with Thor's hammer between scenes and thought it'd be funny to hang it on the coat hook during one of the takes.
In Spider-Man: Homecoming, Tom Holland and Robert Downey Jr. improvised that whole "hug" scene.
In Captain America: The First Avenger, Hayley Atwell instinctively touched Chris Evans' massive pecs while shooting the scene where she first saw him shirtless.
In Thor: Ragnarok, Chris Hemsworth created the whole "get help" gag off-the-cuff.
In Doctor Strange, Benedict Cumberbatch made an impromptu joke about Wong's name and called him "Beyoncé," whom he's never heard of. In the next scene, Wong was listening to Beyoncé as "research."
In Iron Man, Robert Downey Jr. deviated from the script and ad-libbed the famous "I am Iron Man" line.
In Thor: Ragnarok, the "He's a friend from work!" line was actually improvised by a kid from Make-A-Wish who was visiting the set.
In Avengers: Age of Ultron, Jeremy Renner joked about shooting Quicksilver in the back before the camera stopped rolling, and they kept it in.
In Captain America: Civil War, Tom Holland forgot his blocking, so RDJ stayed in character and said "you're supposed to move now so I can sit on the bed."
In Black Panther, Winston Duke decided to make gorilla sounds to assert M'Baku's power when Martin Freeman's character tried to step in.
In Thor: Ragnarok, Chris Hemsworth completely fabricated the whole childhood snake story off the top of his head.
In The Avengers, Robert Downey Jr. always hid snacks around the set for when he got hungry. One day he randomly offered Chris Evans blueberries in the middle of a scene, and they kept it in.
In Thor, Chris Hemsworth ad-libbed the "another!" line after drinking his first sip of coffee, and then he threw the cup on the ground.
And, of course, in Avengers: Infinity War, Tom Holland improvised his final lines before disintegrating and turning to dust.
