Silvia Saint (born Silvie Tomčalová; February 12, 1976) is a Czech former pornographic actress. In 1996, she was Penthouse Pet of the Year in the Czech edition of the magazine, and between 1997 and 2001, she appeared in over 250 pornographic movies.
Tomčalová studied management for two years in Brno, and worked as a manager of a large hotel in the Czech city of Zlín, and in other companies as an accountant and marketing coordinator. She found that the work was financially unsatisfactory, so she moved on to modeling, first lingerie, then nude in magazines, and finally to pornographic films. She wasPenthouse Pet of the Year in 1996 (Czech edition). After her introduction to the American porn industry, she won the People's Choice Adult Award "Best Newcomer" in 1997 and October 1998 Penthouse Pet of the Month (U.S. edition).
Saint starred in a Private Media Group space-themed pornographic film The Uranus Experiment which featured a brief scene filmed in a Russian aircraft flying a parabolic track (similar to NASA's Vomit Comet). The Uranus Experiment features around 20 seconds of Saint and Nick Lang (who portray astronauts living on a space station) having penetrative sex in freefall. The scene was nominated for a Nebula Award, but did not win.
