Yes, they definitely could make a realistic, accurate movie set in a any number of locations, from Juarez to Sinaloa, and over to Tampaluipas, there's an infinite amount of stories to be told, and framed by cartel violence and that general environment, I have a handful of good ideas for scripts....not like they are standing in my way, but I doubt similar ones would even get a second look... because Hollywood prefers to give us snarling, cliche, downright embarrassing versions of these figures, and you get trash like 'Savages', I though 'End Of Watch' did a convincing job with that element of their story though. Unfortunately, I think we will continue to see the antagonists and villains of B rate action movies be mexican drug lords and their henchmen, much like Russians were portrayed in the 80's. The stock bad guy, so to speak.
I think we will see very little of that world portrayed in a meaningful and artistic fashion, directors like Michael Mann, could make a masterpiece with the content though. I think a newer director with a touch for romance epics, could make a classic with the right script, of this concept I thought of, 'Legends Of The Fall' style story, set in the marijuana fields in remote northern Sinaloa, beautiful sweeping scenery, tragedy and family, love and violence.... theres literally so many stories to tell, but we'll keep getting the bullshyt. ....'Traffic' may be the best we will get.
