Ssshhhhh! Quiet down because "A Quiet Place 2" has started filming.

John Krasinski, who directed the smash hit first film and returns to helm the sequel, revealed the news on Twitter by posting a picture of the clapboard for scene one, take one of the movie.

"A Quiet Place" starred Blunt and John Krasinski as parents of a family who are forced to live in near-silence due to a threat from creatures who hunt by sound.

Not much is known about the sequel. Blunt is back as the star, but since her husband's character died in the first film, he won't be back as a cast member (unless there are flashbacks). Millicent Simmonds and Noah Jupe are also set to reprise their roles as their kids.

Cillian Murphy is boarding the movie as "a man with mysterious intentions who joins the family unit." And Brian Tyree Henry may be joining the cast as well.

"A Quiet Place" was a smash success, earning over $340 million at the box office. The sequel is slated for March 20, 2020.
