Actress Karen Black is set to deliver an inspiring message to fellow cancer patients from beyond the grave after filming her battle with the disease to document the toll it had taken on her life.

The Easy Rider star passed away last week (08Aug13) following a three-year fight with ampullary cancer, a rare form of the illness which affects the bile duct.

Now it has emerged that the 74 year old had asked her husband, filmmaker Stephen Eckelberry, to capture her health struggle on camera and he is planning to release it on "the right platform for some kind of presentation", reports America's Globe tabloid.

A friend tells the publication, "She felt she could really help others by sharing her experience... That will be Karen's final curtain call and her inspiring message from beyond the grave. She fought so hard until the very end."
