Yet another trailer has been released for the troubled Winnie - the biopic directed by Darrell Roodt on the life of struggle veteran Winnie Madikizela-Mandela.

Two years after an uninspiring trailer made its way onto the internet, and after premiering the movie to lukewarm reviews at the Toronto Film Festival in 2010, Bishop TD Jakes won't give up.

Jakes, leader of the non-denominational mega-church The Potter's House, took over as executive director of the film in an attempt to build interest in it.

The trailer, unusually long for Hollywood releases at five minutes and four seconds, now has a different soundtrack and different scenes.

The previous trailer was just under four minutes long.

Andre Pieterse, of the Ma-Afrika Films production company, and US producer Michael Mosca, say the film has undergone several changes.

Terence Howard (Nelson Mandela) and Jennifer Hudson (Winnie) still misfire when it comes to accents - especially Howard's, which fails to portray the former president's demeanour and tone when speaking to the masses.

The trailer has Howard shouting at some points, whereas Mandela was characteristically calm.

The film is every bit a soppy love story, with a soundtrack written by Diane Warren, who is best known for writing songs such as Toni Braxton's Unbreak My Heart, Beyonce's I Was Here, LeAnn Rimes' How Do I Live and Celine Dion's Because You Loved Me.

Last month, Roodt told The Times: "It's a good film. Is it the one I made? No, but it is still a great film and I think people should see it."

It is due for release in the US in September, and closer to the end of the year in South Africa.

Pieterse was unavailable for comment yesterday.
