According to Christi herself on the 2023 blu ray commentary track, she was 18 or 19 when she did the movie, so 1977 isn't her accurate birth year. The slate seen in the behind the scenes footage indicates the movie was shot in December 1993, coinciding with her birthday. This likely means she signed her contract at age 18, and then turned 19 as the filming commenced. This would make her birth year 1974.
