Sheryl Lee [SEP] 1986—1993: Career beginnings and "Twin Peaks"
Lee's first television role was as the dead Laura Palmer in the television series "Twin Peaks". To save on money, creator David Lynch intended to cast a local girl from Seattle "just to play a dead girl". The local girl ended up being Sheryl Lee. Lynch asked Lee to audition for him after seeing a publicity photo of her in Seattle from one of the plays she was starring in at the time. "But no one — not Mark, me, anyone — had any idea that she could act, or that she was going to be so powerful just being dead." Indeed, the image of Lee wrapped in plastic as well as her Homecoming Queen-Photo became one of the show's most enduring and memorable images.
