Abdul Karim, one of the Sudanese participants, suffered a breakdown while filming a scene of losing his family in a raid. He had lost his family in Darfur.
There were no lines prepared for the film according to Uwe Boll. In a behind-the-scenes documentary, Boll stated that after all the advice and help the production had received from the many Sudanese extras, he considered it arrogant to hand them a script on what to say. He also believed that the scenes of dialogue would flow more realistically if they weren't scripted.
Because no dialogue had been written for the actors, they had to create their own characters, and do extensive research about Darfur and journalism. This was meant to add to the realism.
In an interview at the Cannes Film Festival, Uwe Boll spoke of how several people playing Darfur victims were indeed from Darfur, and it was hard for them to re-enact scenes of terror in the film.
Research had been done to make the village sets look authentic. According to the producer Chris Roland, they invited a Darfur refugee to come see the film set for himself. He was shown drawings and compositions of the production. The man touched the pictures with his fingers, said 'Darfur' and began to cry.
