Spoiler warning, proceed with caution!
When Venom director Ruben Fleischer set out to adapt the wildly popular comic for the big screen, he wanted it to be a love-letter to longtime fans. Fleischer even copied frames straight from popular Venom comics, making it incredibly likely there are secrets you missed in the film.
A large swath of Venom Easter eggs reference the titular character's place in the Spider-Verse, but they're not there simply to wink at devout fans. As was the case with Spider-Man: Homecoming Easter eggs, Venom looks ahead to the larger superhero universe and to potentially impending movies in the anti-hero's future.
It's refreshing to see a director care this much about their source material, and it creates a fun ride for audiences who know the comics by heart. For everybody else, Venom's Easter eggs are just icing on the deliciously vicious, gooey cake.
In Venom, Eddie Brock's apartment complex is named the Schueller Building. On the surface, it sounds like a fairly innocuous name, but it's actually an intentional callback to Randy Schueller. In the '80s, Marvel ran an open competition for new Spider-Man suit ideas. Schueller wrote into the contest with an idea to give Spider-Man a black suit that would help with stealth and enhance strength.
Marvel loved the idea and actually paid Schueller to write a script. The draft didn't pan out, but Schueller's vision did debut as the infamous Symbiote suit, which soon turned into the villain we all know and love.
At the end of the film, he says he wants to eat tater tots and chocolate. Though Brock is seen consuming tots throughout the film, the addition of chocolate feels like the line comes out of nowhere.
In the comics, however, Venom eats chocolate to help dampen his craving for brains. Both brains and chocolate contain phenylethylamine, which the Symbiote supposedly needs to survive.
There are several moments in Venom where the titular character debates whether or not to eat somebody. In an especially chilling instance, Venom looks one of Carlton Drake's men up and down and utters the creepy line, "Eyes, lungs, pancreas. So many snacks, so little time."
It's a perfectly written line for the character, and it's also directly from Amazing Spider-Man #374.
In the Spider-Man comics, John Jameson is the son of J. Jonah Jameson, editor-in-chief of The Daily Bugle. The spaceship crash scene passes very quickly in Venom, but if you listen closely, you can hear the astronaut who survives the wreck at the beginning of the film called "Jameson."
This isn't just a nod to the comic character, but also his counterpart from Spider-Man: The Animated Series. On the '90s show, Jameson pilots the craft that unwittingly brings Venom to Earth.
