The Spartacus: Blood and Sand star lost his battle with non-Hodgkin's lymphoma last year (Sep11), aged 39, and he invited Foster to chronicle his battle with the disease.
But the filmmaker and her producers have run out of cash and they're asking Whitfield's fans to donate to the project via funding website Kickstarter.com so they can complete Be Here Now.
A statement from Foster and her crew reads: "Be Here Now transcends the subject of cancer and becomes a universal life-lesson about living fearlessly, going for your dreams, embracing each moment and living in the present - despite the potential outcome."
