Sony’s Spider-Man: Into the Spider-Verse is earning rave reviews from critics for its gorgeous animation and irreverent humor. Turns out, that humor persists even after the credits are done rolling.

Now that people have seen the movie, details about how the film unfolds are starting to come out. That includes what happens in the movie’s post-credits scene, which is a major callback to one of Spider-Man’s greatest memes.

WARNING: SPOILERS AHEAD

Turns out, Star Wars actor Oscar Isaac makes a brief (voice) cameo as Spider-Man 2099, a character created in 1992 who goes by the name Miguel O’Hara. O’Hara is a geneticist who attempts to recreate the abilities of the original Spider-Man, later suffering an accident that results in him gaining powers similar to the famed web slinger.

In Spider-Man: Into the Spider-Verse, O’Hara obtains a device that allows him to travel through the multiverse. Naturally, he makes his first stop on Earth-67, which is the same year the 1967 Spider-Man cartoon aired.

There, O’Hara encounters that universe’s Peter Parker, where the two create the famous pointing Spider-Man meme. Mainstream audiences might not understand the reference, but fans of the character will recognize it immediately.

Sony is already planning a sequel for Spider-Man: Into the Spider-Verse, and with Isaac featuring in the post-credits scene, it’s likely he’ll factor into the next film.

Spider-Man: Into the Spider-Verse hits theaters on December 14.
