Oliver Stone's latest film, World Trade Centre, is to be privately screened to police and firefighters who were present through the terrible events of the attack.

According to the New York Post Seattlepi.com police and firefighters have been invited to these screenings this week, a police union is warning their members that this could be a traumatic experience. Even going so far as to say it could cause post-traumatic stress.

"Emotionally, it's important that these men and women have the opportunity to see the film first, though only if they feel comfortable," said Michael Shamberg, the film's co-producer.

I'm with the movie people on this one, the offer of private screenings is a respectful and honest one (as well as a great marketing deal, let's be honest). To claim that the movie could cause post-traumatic stress is a bit strong, at the most it could exasperate it.
