There seem to be quite a few strange scenes in the DC Cinematic Universe, some of which are even difficult for the audience to understand, and even those directors who have participated in the DC series of movies may not understand it.
James Gunn, who is currently directing "Superman: Legacy", when talking about the ending easter egg of the movie "Shazam: Fury of the Gods", he himself can't quite understand why these characters appear.
In the first ending credits of the sequel to Shazam!, Shazam: Wrath of the Gods, Billy meets an invitation from Emilia Harcourt and John Ikonomos to join the superhero team, which is not a "Justice League", but also a "Justice Society" led by justice.
This easter egg connects the previous Black Adam movie with James Gunn's Task Force X: All Assembled, and the HBO series Peacemaker (Gunn's involvement) (both characters appear). But this made the "rolling guide" himself confused, and he hurriedly said, "This is not my decision, nor did I write it."
While DC may want to recreate a more connected DC Cinematic Universe in this way, the plots may be too disjointed for the audience or even the directors themselves.
