There are definitely some direct references and nods. The line from two episodes about emergency reshoots reminded me of 2017's Justice League. The one line about shooting the all-female scene reminded me of the not-at-all shoved in A-Force moment in Endgame.
And do we even need to point out how the guy pulling the strings is obviously meant to be Kevin Feige? He's even wearing a baseball cap all of the time!![]()
