The mother of a 9/11 victim who died in the World Trade Center says she NEVER gave permission for "Zero Dark Thirty" producers to use a voicemail left by her son during the attack.
Mary Fetchet has lashed out to several media outlets ... saying she was shocked and upset when she heard her son's voice featured in the dramatic opening moments of the Oscar nominated movie.
Fetchet's son, Bradley, left the voicemail for Mary while he was on the 89th floor of the World Trade Center.
The studios behind the movie released a statement calling the movie a "tribute" to the victims -- and saying they "initiated contact with a number of families."
Fetchet -- and at least one other family of a 9/11 victim -- aren't buying the explanation and are now demanding an apology.
