In 1975, a then 17-year-old Griffith appeared opposite Gene Hackman in Arthur Penn's film noir Night Moves. She later rose to prominence for her role portraying a pornographic actress in Brian De Palma's thriller Body Double (1984), which earned her a National Society of Film Critics Award for Best Supporting Actress. Griffith's subsequent performance in the comedy Something Wild (1986) garnered critical acclaim before she was cast in 1988's Working Girl, which earned her a nomination for the Academy Award for Best Actress and won her a Golden Globe.

The 1990s had Griffith in a series of roles that received varying critical reception; she received Golden Globe nominations for her performances in Buffalo Girls (1995), and as Marion Davies in RKO 281 (1999), while also earning a Golden Raspberry Award for Worst Actress for her performances in Shining Through (1992), as well as receiving nominations for Crazy in Alabama (1999) and John Waters' cult film Cecil B. Demented (2000).
