So, I have a logistical thing: Stark calls Thor "Lebowski".
Meaning that Jeff Bridges exists in the MCU.
In Iron Man, Tony's mentor, Obidiah Stane, is played by Jeff Bridges.
And when you start six degrees of Kevin Baconing this shit, you get stuff like Hiddleston and Pratt also existing. So, do the heroes just happen to look EXACTLY LIKE THE FAMOUS ACTORS?
