Raquel Welch, Enrico Colantoni will star in Lifetime biopic, 'House of Versace'

Raquel Welch will portray Gianni Versace's aunt in the Lifetime biopic 'House of Versace,' while Enrico Colantoni will play Gianni and Gina Gershon will play his sister Donatella. Raquel Welch recently starred on 'CSI: Miami' and the TV show 'Welcome to the Captain.'

Gina Gershon, Enrico Colantoni, and Raquel Welch have found a fashionable new gig.

Gershon has been cast as Donatella Versace in Lifetime's upcoming biopic "House of Versace," while "Veronica Mars" alum Colantoni will play Donatella's brother, slain fashion icon Gianni Versace, and Welch will play the pair's Aunt Lucia.

The movie, based on the book "House of Versace: The Untold Story of Genius, Murder and Survival" by Wall Street Journal reporter Deborah Ball, will track Donatella's struggle to take over her brother's fashion empire after his 1997 slaying.

"At first ridiculed by critics worldwide, Donatella falls victim to drug addiction and nearly bankrupts the company," Lifetime said of the project in a release. "With the help of her family, including daughter Allegra, Aunt Lucia (Welch) and brother Santo (Colm Feore), she enters rehab to confront her demons and soon comes back stronger than ever to re-ignite the beloved Versace brand with her own vision and builds one of the most powerful and influential fashion houses ever known."

"House of Versace" is slated to premiere Oct. 5 at 8 p.m.

Following the premiere, Lifetime will air the hour-long documentary "Versace: Beyond the Headlines," about Gianni's start and rise in the fashion business.
