Susan Bernard, an actress in soap operas and low-budget films who also promoted her photographer father’s vast archive of images of Marilyn Monroe, died on June 21 at her home in the Hancock Park section of Los Angeles. She was 71.

Her son-in-law, Mark Fortin, said that she died unexpectedly, apparently of a heart attack.

As an actress, Ms. Bernard was probably best known for her role at the age of 16 in the Russ Meyer cult favorite “Faster, Pussycat! Kill! Kill!” (1965), the tale of three go-go dancers on a murderous spree in the California desert. Ms. Bernard played a woman whom they kidnapped.

She also starred in “That Tender Touch” (1969), about the breakup of a lesbian couple in Southern California.

After her acting career was largely over, she founded and became the president of Bernard of Hollywood Publishing/Renaissance Road Inc., a firm that preserves, exhibits and licenses the work of her father, Bruno Bernard, who died in 1987.
