Farrah fawcett at The 'Late Night With David Letterman ' Show. New York City, USA - 06.04.05

The actress has been battling anal cancer, which recently spread to her liver, and has suffered complications from an unrelated medical procedure performed in Germany.

Her two-year fight has been captured on video by best pal Alana Stewart and now the footage will make up a two-hour special, called Farrah's Story.

Fawcett's on/off partner Ryan O'Neal and her former Charlie's Angels co-stars Jaclyn Smith and Kate Jackson will appear in the programme.

The actress says, "This film is very personal. At the time, I didn't know if anybody would ever see it. But, at some point, the footage took on a life of its own and dictated that it be seen."
