It's a sad day in Hollywood. Laura Ziskin, best known for her work as a producer for the 'Spider-Man' film franchise, passed away Sunday after a long battle with breast cancer. She was 61.

According to E! Online, in addition to her work on 'Spider-Man,' she also served as a producer for the 1990 hit 'Pretty Woman.' In 2002, she was also the first woman to serve as a solo producer for the Academy Awards -- a role for which she won several Emmy Awards.

Ziskin was diagnosed with Stage 3 breast cancer in 2004 and decided to co-found the cancer-fighting organization Stand Up To Cancer (SU2C).

"It is with great sadness that we share with you the news that our colleague and dear friend Laura Ziskin, co-founder of Stand Up To Cancer, passed away peacefully today at her home in Santa Monica, California," the organization said in a statement.
