The lawsuit brought by movie investors seeks more than $8 million. They claim Hilton reneged on a contract to promote the film, including its DVD release. They say she refused interviews and other promotional opportunities.
Hilton contends she plugged the movie extensively and met the contract's requirements. She says the producers made unreasonable demands for appearances when her schedule was full.
The movie cost $7.5 million to make but earned only about $2.9 million.
