No One Will Save You is a 2023 science fiction horror film written and directed by Brian Duffield and starring Kaitlyn Dever as Brynn, a woman alone during an alien home invasion. The film is famous for having almost no dialogue, so the aliens communicate through clicks, chirps and guttural noises instead of speech. Clips of those sounds spread online as reaction audio and horror edits, where the chirp became shorthand for an unseen extraterrestrial threat approaching without any warning at all for its victim.
