The key to becoming memorable is to excel in whatever field you're given. Sybil Danning realized quite early on that she was never going to become a major Hollywood box office draw, so she decided to become the Queen of the B movie instead. That's actually a step up from how she spent much of the 1970s, which was making softcore pornography in Germany.
Danning was 28 by the time the 80s began and running out of time to get her career kickstarted. She'd moved to Hollywood in 1978 in the hope of breaking out of her erotic mold, and she achieved that aim. Films like 'Howling II: Your Sister Is A Werewolf,' 'Reform School Girls' and 'Chained Heat' may not have been Oscar winning classics, but they weren't porn. Sadly, her movie career was totally derailed by a bad back injury in 1990.
