10 Important MCU Details That Are Almost Never Mentioned

10. The Illuminati Have Been Lurking For Some Time

Much of the marketing surrounding Doctor Strange's second, and seemingly much more horrific, solo outing within the Marvel Cinematic Universe has centred around a certain well-known collection of individuals finally rearing their big screen heads.

But, in truth, this Marvel secret society of heroes by the name of The Illuminati, boasting members such as Charles Xavier, Tony Stark and the aforementioned Strange in the comics, may have actually been knocking around in the universe we've grown accustomed to for quite some time already. As evidenced in a blink-and-you'll-miss-it shot during Iron Man 2's courtroom sequence, Tony Stark's typically advanced mobile can be seen housing an app titled "Illuminati".

Sure, it may just have been a cheeky wink or Easter Egg of sorts courtesy of Feige and Jon Favreau from more than a decade before Multiverse of Madness' release. Yet, the MCU does have a habit of paying off this type of throwaway tease or just writing a piece of foreshadowing into reality later down the road.

Again, the fact a plot development this potentially game-changing has only been granted a millisecond of screen-time does seem to suggest Marvel weren't entirely all-in on the eventual Illuminati introduction back in 2010. But if this was actually the plan all along, then you do have to wonder why more winks and nods to their impending arrival haven't been shuffled into various MCU entries over the last 12 years.
