15 MCU facts that are actually true

On set

1. The shawarma scene didn’t exist until after the premiere. Joss Whedon wrote it late; it was shot the day after The Avengers premiered in April 2012. Chris Evans had grown a beard for Snowpiercer, so he hides his chin behind his hand — and a prosthetic jaw.
2. Robert Downey Jr. hid food all over the Avengers set so he could snack between takes. When Whedon saw him eating, he kept it in — the blueberries Tony offers Banner and Cap were Downey’s own.
3. “I am Iron Man” was improvised. The line that ended the first film and set the MCU’s tone wasn’t in the script; Downey ad-libbed it and Jon Favreau kept it.
4. Thor’s eyebrows were bleached for the 2011 film to match Hemsworth’s dyed-blond hair — the detail fans spotted and never let go of.
5. Chris Pratt’s opening dance in Guardians to “Come and Get Your Love” was Pratt’s own choreography, filmed with James Gunn dancing off-camera to keep his energy up.
6. Rocket is two actors. Bradley Cooper provides the voice, but James Gunn’s brother Sean Gunn performed Rocket on set, crawling around in a motion-capture suit so the other actors had someone to react to.
7. Benedict Cumberbatch played Dormammu too. The “I’ve come to bargain” time-loop villain in Doctor Strange is Cumberbatch in motion capture, with his voice deepened in post.
8. Ant-Man had a real quantum physicist. Caltech’s Spyridon Michalakis consulted on the film and coined the term “Quantum Realm” for the MCU.

Easter eggs

9. Cap’s notebook changes by country. In The Winter Soldier the US list has Star Wars/Trek, Nirvana and Thai food; the UK list has The Beatles and the 1966 World Cup; Australia gets AC/DC and Steve Irwin; Russia gets Vladimir Vysotsky.
10. Stan Lee appeared in every MCU film from 2008 to 2019 — as a Hugh Hefner lookalike in Iron Man, a FedEx driver in Civil War, and a passenger on the Benatar in Infinity War. His final cameo, in Endgame, was filmed before his death in November 2018.
11. Ben & Jerry’s made the Avengers flavours real. “Hunka Hulka Burning Fudge” and “Stark Raving Hazelnuts”, joked about in Age of Ultron, went on sale in 2019.
12. Tom Holland is a known spoiler risk, so Marvel gave him fake scripts and didn’t tell him what Infinity War was about. Mark Ruffalo accidentally live-streamed ten minutes of Thor: Ragnarok from his pocket.

The numbers

13. The MCU is the highest-grossing film franchise in history, past $30 billion worldwide — more than Star Wars and Harry Potter combined.
14. Deadpool & Wolverine (2024) is the biggest R-rated film ever, 2024 at about $1.34 billion — proof the MCU could survive a swear word.
15. Downey is back — as the villain. 2026 Announced at Comic-Con 2024, Robert Downey Jr. plays Doctor Doom in Avengers: Doomsday (18 December 2026), alongside Patrick Stewart and Ian McKellen reprising the X-Men’s Xavier and Magneto.

Myth busters

Four MCU “facts” the internet made up

✗Thor eats “Asgardian Ale” ice cream in Endgame.
No such flavour exists in the film. Thor drinks beer; the Ben & Jerry’s gag is in Age of Ultron, and those flavours are Hulk and Stark themed.

✗Peter Parker texts Tony the word “friens” as an autocorrect joke.
No such line or text appears in Homecoming. Pure invention.

✗James Gunn wrote Rocket a database of 80 insults.
No interview, script or commentary mentions this. Rocket’s insults are just good writing.

✗Downey ordered a real pizza on set for the delivery-guy scene in The Avengers.
There is no pizza delivery scene in The Avengers. The real improvised-food story is the hidden blueberries.
