Because of the positive test, cast members have been sent into routine isolation for 14 days.
Post quarantine period, the cast members and production will return.
Don't Worry Darling is a thriller/drama. Collider has reported that Florence Pugh will play an "unhappy housewife (Alice) who slowly begins to question her own sanity when she starts to notice strange occurances in her small, utopian community in the California dessert."
Harry, who apparently landed the role after actor Shia Lebouf pulled out, will play her "picture-perfect husband (Jack), who loves her dearly, but is hiding a dark secret from her".
Deadline added that it's a "psychological thriller set in an isolated, utopian community in the 1950s California desert."
The script has been written by Booksmart writer Kate Silberman, and produced by Twilight director Catherine Hardwicke.
Olivia Wilde will direct and star in the film.
While fans had been hoping for a 2021 release date, there is no official confirmation as to when the movie will be released.
With this new set back, the release date is even more up in the air.
