Los Angeles, Aug. 1 (AP): Paris Hilton is going from jailbird to songbird with a role in a movie musical about organ harvesting.

Hilton will co-star with Paul Sorvino and Alexa Vega in ``Repo! The Genetic Opera,'' which begins shooting in September in Canada, Hilton's publicist, Elliot Mintz, said Tuesday.

It will be Hilton's first role since she completed a 23-day stay in jail for violating probation in an alcohol-related reckless driving case, Mintz said.

The horror rock opera, based on a stage musical, is set in a plague-ravaged future where people can purchase new organs on the installment plan from a corporation called Geneco. The catch is that if the payments stop, the organs are repossessed.

Hilton will portray the fame-seeking daughter of Geneco's owner (Sorvino).

``We saw many actresses for the role, and Paris sang it better than all of them,'' ``Repo!'' producer Carl Mazzocone told the Hollywood trade paper Daily Variety in Monday editions.

The director, Darren Lynn Bousman, also praised Hilton.

``I have auditioned at least 30 actresses for this role - Paris came in and owned it,'' he told Variety. ``She is this role.''
