Kiwi actress Rose McIver will replace Mad Men star Kiernan Shipka in the sequel to the controversial film Flowers in the Attic.

McIver, who has appeared in Sir Peter Jackson's Lovely Bones and US television series Masters of Sex, has been cast as Cathy Dollganger in the made-for-TV movie, Petals on the Wind, according to Hollywood Reporter.

The series, which begins with Flowers in the Attic, tells the story of the Dollganger children, who are locked in their grandmother's attic for years after their father dies, forcing their mother to rely on her rich parents. Over time, Cathy and her brother Chris begin a sexual relationship, before they finally escape.

Based on V.C. Andrews' young adult novel from 1980, the sequel picks up events of the family drama 10 years later, forcing a major recasting of the characters. Shipka, 14, plays Sally Draper in Mad Men.


Set in 1971, Petals on the Wind follows Cathy and her two younger sisters as they try to forget their mother's abuse. Followed by disaster, McIver's character plots and schemes to get ultimate payback.

Hollywood stars Heather Graham and Ellen Burstyn, who play the children's mother and grandmother, will reprise their roles for the Lifetime channel production. Filming is expected to begin soon.

When it aired in the States in January, Flowers in the Attic pulled in 6.1 million viewers, making it the top-rated TV movie on basic cable among adults aged 25-54 since November 2012.

McIver is currently starring as Tinkerbell in TV2's hit fantasy drama Once Upon a Time.
