RZA, who is also the late hip-hop star's cousin, saw a teaser video Rayshawn and the late Wu-Tang Clan member's widow put together and insists project has great potential.

"I think it's a great idea, and there has been talk about it," he tells RollingStone.com. "There are a few wheels in motion with one done by our first cousin Rayshawn; he was the young guy there watching everything that happened. Him and ODB's wife have been talking and he has a pretty interesting script.

"I just saw a 12-minute teaser that he shot about a year ago and it felt pretty f**king cool. I watched it and was like, 'Wow, you may have something here.' He has the best thing that I've seen so far."

"Straight Outta Compton showed that hip-hop is a marketplace in cinema," he adds. "I always believed that the art we was creating was audio-visual, and it was headed towards visual-audio... I'm glad that a movie like that breaks out and does such numbers that it's almost undeniable. It showed that with the proper team and marketing, many of us out here who grew up on this music would love to see the inside makings of those stories."

The project has been in development since 2011 and Rayshawn asked RZA to direct the film, but he's not sure if he wants to take on the project.

"I wouldn't mind not doing it and I wouldn't mind doing it," he continues. "There are very few people who know the real him as much as me. So it would be something that I would be honoured to do, but there's a lot of moving parts to it. If those moving parts don't go in sync with me, I'll still be on it just to see it happen, talk to whoever's doing it and give them my interviews or whatever they need to help make this story as great as possible."
