Tom Hanks reportedly sent a letter to the Egyptian director, congratulating him on his extremely well put-together film.
Diab also wrote that Daniel Craig, the face behind James Bond, sent him a similar letter, praising his work as it is a true reflection of Egypt as a country.
Set entirely in a 8 meter police truck, the film's plot depicts a number of detainees from different political and social backgrounds being brought together during the turmoil that followed the ousting of former president Morsi from power.
After having screened at the Cannes Film Festival in May, the film received international recognition for its message about chaos and cruelty. The film is set to be released in Egyptian theaters on July 27.
