Extremely Loud and Incredibly Close hit the big screen yesterday, and as we know from the trailer, it tends to make the room you are in very dusty. While everyone may be reaching for the Kleenex while watching the movie—an adaptation of Jonathan Safran Foer's novel about a boy who loses his father on September 11th—a Lower Manhattan non-profit has issued a warning to survivors and family members of those who died that day.

The Tribute WTC Visitor Center sent out an email before the movie's release saying it could trigger flashbacks. They wrote, "If your intentions are to go and see this film, you should be prepared to possibly relive past issues or have difficulty handling those you have currently, due to [the] 9/11 attacks. Use your own discretion when deciding if this incredibly inspiring and moving film will give you an experience [that] we would want you to walk away with. Be prepared for a very sobering and real life experience."

According to DNAInfo, the movie's stars, Sandra Bullock and Tom Hanks, visited the center before filming the movie, also taking a tour of the area with 9/11 survivors, victims' families, and first responders. On their Facebook page, the center wrote:

For some, this may hit too close to home, but if you have the opportunity to see the truly inspirational new film, Extremely Loud and Incredibly Close, starring Tom Hanks, Sandra Bullock and a very talented young man by the name of Thomas Horn, you should take an afternoon.

The Tribute Center's founders, Lee Ielpi and Jennifer Adams, had a heart-warming experience with Bullock and Hanks when they came on a Tribute walking tour before filming and Lee & Jen just attended the preview for the film. They were incredibly moved by the film and how relationships and loss are portrayed in families affected by the 9/11 attacks.

Here's that trailer again:
