10 Obscure MCU Movie Secrets That Took Years To Discover

10. Tony Stark's Illuminati Phone App - Iron Man 2

Back in 2017, Redditor bowj discovered a devilishly well-hidden Easter egg in Iron Man 2, so cleverly concealed that it took someone almost eight years to find it.

When Tony Stark (Robert Downey Jr.) is attending a Senate hearing and starts tinkering around on his phone, look closely - very closely, that is - and alongside apps for S.H.I.E.L.D. and his various prototypes, you might notice an app labelled "Illuminati."

The app's logo even matches that of the secret superhero organisation's logo from the comics, and while this was clearly just a fun wink-wink nod to comic book fans, it is an interesting discovery in light of the Illuminati's first "proper" MCU appearance in Doctor Strange in the Multiverse of Madness (albeit on an alternate version of Earth).

Given that Tony's phone screen is shown for mere fractions of a second and the text is extremely hard to read amid the screen's movement, it's not terribly surprising that it took someone so many years to find it.
