Karen Black lent her name and accepted lead billing in CHILDREN OF THE NIGHT, a 1991 horror/spoof that looks as if it went straight to video in the U.S. It was all pretty generic, as this trailer shows:
In 1992, Black had a small role in the direct-to-video action film QUIET FIRE and reprised her role from the THE ROLLER BLADE SEVEN in the two sequels--RETURN OF THE ROLLER BLADE SEVEN and THE LEGEND OF THE ROLLER BLADE SEVEN.
Black had a small role in the 1992 spy action film DOUBLE O KID, starring the late Corey Haim. The film went direct to video in the U.S., and is currently available on YouTube. Composer Misha Segal's main title was a direct steal of the James Bond theme. See the sequence starting at 3:00 in this clip.
