Circumstance: Mainstream actress turned adult film star

After making just a handful of B-grade horror flicks in the mid/late '80s (as Kim McKamy), Gere made the jump into XXX territory, and went on to become one of the most popular stars of the '90s. She was also used as a body double in Basic Instinct (1992) and Indecent Proposal (1993).
