Playing the blue-lipped corpse of Laura Palmer, washed ashore on television's Twin Peaks, was not easy. ''Hours and hours and hours of lying perfectly still'' is how SHERYL LEE recalls the role.

The David Lynch movie has already opened in France – it hits German screens in August – and since May has become a cult favorite of the Japanese, who cannot get enough of the Peak experience.
