James Gunn says that some fans have come close to finding the super secret Easter egg in Guardians of the Galaxy, but there’s another one hiding in the sequel, Guardians of the Galaxy Vol. 2.
Gunn also says that Guardians of the Galaxy Vol. 2 contains another well-hidden Easter egg, and that this one will be even more difficult to find.
One thing that fans love about the Guardians of the Galaxy movies is the abundance of references to Marvel lore.
Details of these Easter eggs can be found on countless websites, however one Easter egg has somehow gone unnoticed, even after three years.
