Variety has exclusively learned that Australia’s Seven Studios has begun principal photography on the series “Secret Bridesmaids’ Business.”

The show stars Abbie Cornish (“Three Billboards Outside Ebbing, Missouri”), Katie McGrath (“Supergirl”), and Georgina Haig (“Once Upon A Time”).

In the series, a bride’s perfect wedding turns deadly after one of her bridesmaids unknowingly invites a malevolent stranger into their lives, triggering a destructive chain reaction that blows open a hidden world of secrets. As the show unfolds, the power of female friendship could be the difference between life and death.

Cornish plays Melanie, who appears to have an idyllic life: she’s a mother and wife, with a successful career and a beautiful home. However, when her life choices are put to the test by some harsh home truths, her ideal world starts to spiral out of control. McGrath is Saskia, a fast-rising lawyer and an arresting, high-octane British truth-bomb. She is relentlessly intelligent and fiercely loyal. A bisexual woman, Saskia defies pigeonholing and holds a secret that could mean the end of friendship with her best mate, Olivia. Playing Olivia is Haig. Olivia’s near-death experience with leukemia has made her determined to follow her dreams. She’s vibrant, witty and an optimist. When she discovers something dark about a loved one, it drives her to bury her own secret to protect those around her.

The cast also includes Alexander England (“Alien: Covenant”), Dan Spielman (“Deep Water”), Oliver Ackland (“The Originals”), Annie Jones (“Neighbours”) and Nicholas Bell (“A Place To Call Home”).
