I'm not aware of a widely known 'WOM as N in Gold: True Story' specifically. There could be many stories in the gold industry that involve word - of - mouth in some way, but not one that is commonly known by this rather unusual title.
Yes, it's a true story. The movie depicts the long and complex journey of a woman trying to reclaim a painting that was stolen from her family during the Nazi era. It involves legal struggles, historical research, and a fight for justice that actually happened in real life.
