Justice League: 29 Easter Eggs & References You Need To See

4. "A League Of Our Own"

The film's aforementioned post-credits scene sees Deathstroke meeting up with Lex Luthor on a boat in an undisclosed location, where upon hearing of the Justice League successfully repelling Steppenwolf, he declares that they need "a league of [their] own".

On one hand this is clearly a reference to the hit 1992 baseball movie A League of Their Own, but of course, Luthor is also not-so-subtly inferring that he, Slade Wilson and others will form their own villainous stable, most likely the Legion of Doom, in the near-future.

Whether the wider DCEU will survive long enough for this to come to fruition is a whole other question, though.
