10 Most Meta MCU Moments Ever
1. Stan Lee Is A Watcher Informant
Prior to his 2018 death, Stan Lee was of course a staple of every single MCU movie by way of his customary wink-wink cameos.
Eventually a fan theory started doing the rounds online that Lee might actually be playing the very same character across all of his MCU appearances: Uatu the Watcher.
In the comics, Uatu was an alien tasked with observing human activity on Earth and the Solar System, so having Lee be playing this character in a series of humanoid disguises certainly made a ton of sense.
And while most fans assumed this would never be formally confirmed, in Guardians of the Galaxy Vol. 2 it was heavily implied to more-or-less be the truth.
Lee cameos as a man seen speaking to the Watchers, and can be briefly overheard discussing his time working as a FedEx delivery man, nodding towards his cameo as such in Captain America: Civil War.
Though Lee was ultimately credited as a Watcher informant rather than Uatu himself, it was still an incredible tip of the hat towards creative fans and their barmy theory, confirming Lee to have indeed been playing a single character for his entire MCU tenure.
