Clash, which opened the Un Certain Regard section at the 69th annual Cannes Film Festival this year, positions the viewer on the inside of an Egyptian police riot van in 2013, when Egypt's first freely elected president, Muslim Brotherhood member Mohamed Morsi, was overthrown by the military after a divisive year in power. The country later outlawed the group, branding it a terrorist organization.Director Mohamed Diab, who had wanted to make a film about the revolution since the first day of the uprising, focuses on a group of people from all walks of life who are pushed into a police van after having been arrested in one of the many clashes that took place around Cairo. The van is filled with demonstrators, passers-by and journalists who have nothing but one cell phone that they battle over, a camera, a razor, and a primitive urinal.  While they helplessly observe the full-blown civil war taking place on the streets around them, tensions inside the van rise. Some of the detainees support the Muslim Brotherhood while others stand with the military. But the film doesn’t choose who is right or wrong. Instead it focuses on the rage, unwillingness to back down and social injustice. However, the longer these people stay in the van, their differences gradually disappear and their main goal suddenly becomes the same: to exit the police van safely and survive. The film is written by Mohamed Diab and his brother Khaled Diab who took part in the 2011 revolution. It took them two years to finish the screenplay, however, the final version they reached was not the one they used for the film. After rehearsals undergone by 25 actors over the course of six months and taking their notes into consideration, the film had 13 full drafts. Clash is Mohamed Diab’s second directorial project after 678, which he also wrote and which won over 20 international awards. In 2014, he wrote the screenplay for the black and white film Décor and El Gezira 2, which was also a box-office hit.
