The Simple Life
is over for Paris Hilton
, but she has already lined up a juicy new role in the big-screen musical Repo! The Genetic Opera
Hilton is joining Alexa Vega and Paul Sorvino in the cast of Repo!
, a musical thriller from Saw
-makers Twisted Pictures and Lionsgate, according to Variety.
The news comes as E! Entertainment Television has decided not to renew The Simple Life
, the reality show in which Hilton starred with on-and-off pal Nicole Richie for five seasons. The program ran initially on FOX before being picked up by E!, and the series finale is slated for August 5.
Instead of playing herself, the 26-year-old heiress will play daughter to Sorvino's villainous organ-transplant magnate in the futuristic flick. The musical is set in 2056 and centers around a mysterious plague that threatens the survival of the human race. The film is being directed by Darren Lynn Bousman, who also helmed all three Saw
Bousman said Hilton floored him when she auditioned. "I have auditioned at least 30 actresses for this role," he tells Variety
. "Paris came in and owned it. She is
Producer Carl Mazzocone of Twisted Pictures adds: "We saw many actresses for the role, and Paris sang it better than all of them."
In other news, Hilton has put her Hollywood Hills home on the market for $4.25 million, according to The Wall Street Journal
The residence, which Hilton bought in 2004 for just under $3 million, played a cameo role during a tough summer for Hilton. On June 7, a media circus descended on the Hilton house
after the heiress was released (only briefly, it turned out) from an L.A. County jail to serve house arrest in her probation-violation case.
Days after completing her prison sentence, Hilton leased a $2.9 million beach house in Malibu
, where she has been staying.
The media frenzy of early June upset Hilton's neighbors in the Hills. But Hilton's aunt, Kyle Richards, told the Journal
that her niece's decision to sell was not related to that incident.
"I'm sure they'll be happy to see the paparazzi go, but that had nothing to do with it," Richards said. "She can't control the people who are outside."
Richards said Hilton simply wants more space – preferably a larger house in a gated community or one with a long, gated driveway.
The property in the Hills measures 3,000 square feet on a 7,000-square-foot lot, the Journal
reports. Built in 1926, it has a pool, a Jacuzzi and a waterfall.
