Wilsey reportedly took her stage name from Savannah Smiles (1982), a movie she enjoyed. She died in 1994 in the hospital after a suicide attempt.
Wilsey also appeared in a variety of minor roles in B movies (mostly comedy, horror and/or scifi) wherein she was credited with her real name. These roles included The Invisible Maniac (1990) and Camp Fear (1991).
She also had a credit for her performance on a Soundtrack in the video The Spectacle (1991).
Wilsey committed suicide in 1994 by shooting herself after a car accident. On the evening of July 11, Wilsey was involved in an auto accident with her Corvette, wherein she reportedly broke her nose and injured her face. Upset over the accident, she went home to Universal City, asked a friend to walk her dog, and then called her manager, Nancy Pera. It was Pera who later discovered Wilsey in the garage of Wilsey's home.
Wilsey became involved in a long-term relationship with fellow pornographic Actress Jeanna Fine, with whom she later claimed to have fallen deeply in love. In a 1999 interview, following the airing of the E! True Hollywood Story about Wilsey's life and death, Fine commented: "We had an ongoing, on-again, off-again, volatile, loving relationship. At that time I was having a lot of problems myself. Between [male porn actor] Sikki Nixx and Savannah pushing and pulling, I pretty much at one point ran away from them both. I couldn't take it any longer. But I feel I left her behind when she needed me most. It's very sad."
