CECILIA Cheung is facing a boycott threat from a Chinese production company if she does not finish filming The Lady General of the Yang Family.

Major Chinese newspapers reported that Shanghai Film Studio, the second largest film production house in China, had threatened to withdraw its investment of the film if it was not wrapped up by the end of the month.

Cheung was scheduled to shoot 47 sets but discontinued after completing only 31.

This agitated the production house, which threatened to boycott all films by the Hong Kong actress.

"The boycott is expected to affect Cheung's reputation as an actress," one newspaper reported.
