Paris Hilton is to add another movie role to her portfolio - she has been lined up for a new film by acclaimed director Todd Solondz.

The socialite will act alongside Allison Janney, Charlotte Rampling and Paul Reubens in the as-yet-untitled project about a group of dysfunctional characters.

The movie is described as "part-sequel, part variation" to Solondz's hit 1998 tale Happiness and filming is already underway in San Juan, Puerto Rico.

Hilton's previous big screen experience includes the 2006 horror film House of Wax and more recently the rock opera musical Repo! The Genetic Opera, which is currently on limited release in the U.S.
