Venom’s Kryptonite
When Eddie’s explaining the ins and outs of the Venom symbiote, the infamous topic of its big weakness – soundwaves – comes up. Anne repeats the information by saying: “So sound is its kryponite?” This is a weird little meta easter egg that tells us the DC universe is fictional in Venom‘s Marvel-ish universe. It also recalls the line from 2002’s Spider-Man when Tobey Maguire tried to get his webs going by saying “Shazam!”
We also learn what Venom craves. There’s a running gag through the film in which the symbiote has a hunger for human heads, leading him to munch on the craniums of various bad guys. In Venom‘s final scene, Eddie manages to convince his other half that it can’t eat anyone it wants. Venom reluctantly agrees, as long as Eddie picks up some chocolate from the store.
This harks back to the time when Venom got hooked on chocolate in the comics. When Eddie was trying to curb Venom’s homicidal tendencies, he discovered that the symbiote needs to consume the chemical phenethylamine, which is either found in the human brain or in a bar of chocolate.
