The Dilophosaurus became famous through Jurassic Park, released in 1993 and based on Michael Crichton's novel. In the film the dinosaur is shown as a small predator with an expanding neck frill and venom spit, a creative version created for the story. Its encounter with Dennis Nedry starts with curious chirps before turning into an attack, which is why the playful call is remembered so well. Clips of its trills and hisses later spread across meme edits, dinosaur videos and soundboards, where the cute call is now used on its own for surprise and comedy.
