Rahimi, who directed Shakur's I Ain't Mad at Cha and 2 of Amerikaz Most Wanted videos, has turned to fans to help him raise the $300,000 (£200,000) he needs to complete 7 Days via crowdfunding site IndieGogo.com.

He has teamed up with Preston L. Holmes, who worked on the rap icon's movies Juice and Gridlock'd, to produce the film.

In a video posted to Indiegogo, Rahimi says, "This isn't a documentary... This is my experience; my story. 7 Days is a narrative feature film about the week I sat security for Tupac in the hospital. The script incorporates never-before-seen footage of 'Pac that I shot weeks before his demise."

The first fan to donate $50,000 (£33,300) to the cause will receive an 18-karat gold replica of the rapper's "euphanasia" chain.

The campaign runs until 2 July (15).
