A woman with dark curly hair looks back in dread in a cluttered loft laboratory beside a riveted telepod, a fly crawling on its glass.

Be afraid. Be very afraid.

What it means

Our interpretation.

It is a horror poster line that outgrew the poster: a cheerful instruction to worry. Fans say it about anything from a looming deadline to a bad forecast, usually in a mock tremble. The film's body-horror story of a man who loses himself gives the words a real chill under the joke, which is why it still lands.

Spoilers for The FlyShow the scene

Veronica says it in David Cronenberg's The Fly (1986), and it became the film's marketing tagline. In the film, science journalist Veronica Quaife is drawn into the work of scientist Seth Brundle, who has invented teleportation pods and tests them on himself. A fly in the pod fuses with him, and he slowly becomes the creature he calls Brundlefly, losing his human reason and compassion. Veronica learns she is pregnant by him and fears what the child will be. The tagline became so ingrained in popular culture that many people who use it do not know it comes from the film.
