Tomčalová studied
management for two years in
Brno, and worked as a manager of a large hotel in the Czech city of
Zlin, and in other companies as an accountant and marketing coordinator. She found that work financially unsatisfactory, so moved on to modeling, first lingerie, then nude in magazines, then pornographic films. She was
Penthouse Pet of the Year in
1996 (Czech edition) and, after her introduction to the
American porn industry, in
1997, and again in
1998 (U.S. edition).
Saint's early films were shot in Europe, many for
Private Media. Later, she moved across the Atlantic where she spent over three years in the United States. She became known for specializing in anal sex in scenes that left her anus gaping wide open.
Saint, along with
Monica Sweetheart, Lea De Mae and
Daniella Rush appeared in director Frank Thring's
The Academy (2000). The foursome came to be known in the adult industry as the
Czech Dream Team.
On
March 19, 2001, Saint announced that she was leaving the porn industry after ending an off-screen abusive relationship with porn star
Mr. Marcus and moved to
Prague, Czech Republic. However she still performed in many girl-girl scenes after 2001.
Saint was awarded a lifetime achievement award at Torino Sex 2005,
Turin’s second annual Delta of Venus Fair.
In 2006, Saint won the rights to the Internet
domain name sylviasaint.com from a
cybersquatter in a lawsuit.
