If are film was to be produced we would need a big media institution like Sony, as for are war film to be realistic to real events we would need alot of money for special effects. They could also distribute are film and promote in many countries as war films are popular in many countries like america. Sony are experienced in advertisment and would be able to advertise ares through tv adverts, posters, billboards, internet adverts etc, and be able to target are target audience. They have done this with other big films like Qauntum of Solace.
