The enigmatic trailers and posters for Olivia Wilde's Don't Worry Darling have given us a seductive yet unsettling preview of what to expect from the actress and director's sophomore feature picture.

Since the release of the first eerie teaser trailer, fans have been captivated by the retro design and thrilling ensemble, which includes Academy Award winner Florence Pugh,

pop star-turned-actor Harry Styles, and Chris Pine. 

The charm and elegance seem to be eroding with each new advertising addition, yet the same crooning lullaby supports each one.

In an interview with Variety, actress Wilde said that musician Styles provided a spooky original song to the movie, and that Pugh sings the song.

After making her feature film debut in 2019 with the coming-of-age comedy Booksmart

Wilde now offers fans a surreal psychological thriller with a star-studded cast.

Wilde was enamoured with Pugh's portrayal of her frenetic main character Alice in Ari Aster's sunny horror Midsommar and was happy to be able to cast Styles as Jack alongside Pugh as a result of his tour cancellation. 

In a stroke of luck, it turns out the musician,

who made a name for himself as an actor in Christopher Nolan's Dunkirk, was able to use his musical skills for the movie when he noted the script frequently referred to "the trigger song" (or something similar).
