Following on the heels of gay porn star Jack Wrangler's death, (in)famous porn star Marilyn Chambers died Sunday. She was 56. According to reports, her 17-year-old daughter found her body at her northern Los Angeles County home. Chambers, who once modeled for Ivory, "was among the first porn superstars when the stag films of the 1940s through 1960s gave way to the more polished sex films of the 1970s." Some of her well-known titles include Behind the Green Door (1972), Insatiable (1980), and The Marilyn Diaries (1990). She also starred in David Cronenberg's low-budget Rabid, but was unable to make a successful transition to mainstream films.
