He's doing a good job of keeping his Nelson Mandela project under-wraps, even as production has been underway for a bit. Little info has surfaced about it, so we've had really nothing of substance to report. 

I'm one of those who has had trouble picturing Idris Elba as Nelson Mandela (young and/or old), so I'm looking forward to seeing the first footage from the film to see how well he's able to convince me.

Naomie Harris is playing Winnie Mandela by the way, in a film the filmmakers are calling the "the largest South African production ever mounted!"

Justin Chadwick is directing from a script based on Long Walk to Freedom – the autobiographical work written by Nelson Mandela himself, which highlights his early life, coming of age, education and 27 years in prison.

The project will reportedly have an "epic sweep," from a script written by Gladiator, Shadowlands and Les Miserables writer William Nicholson.

By the way, director Chadwick and Harris have worked before in the 2010 drama The First Grader about a Kenyan villager and ex Mau Mau freedom fighter.

But while we wait to get some footage of Idris as Nelson, and Naomie as Winnie, here's a behind-the-scenes look at a music video Idris Elba directed while in South Africa, shooting his Mandela film.

It's actually for his own music – a track titled Robot. I don't think this marks Idris' directorial debut, but directing isn't something he's done much of; although he's said previously that he definitely plans to eventually direct feature films:
