During the film, the three characters take a dangerous journey down a river in a boat and the mother strictly instructs the unnamed children not to remove their blindfolds, or else they will die.
Sounds like a challenge to me.
At least, that's what some internet users thought. Some viewers took to social media posting photos and videos of them doing the so-called Bird Box Challenge. Even some breakfast TV hosts got in on the action.
Netflix took to Twitter to implore people not to get carried away with the challenge.
"Can't believe I have to say this, but: PLEASE DO NOT HURT YOURSELVES WITH THIS BIRD BOX CHALLENGE," it wrote from its US account.
As Netflix says, maybe don't "end up in the hospital due to memes".
