A film looking back at the struggles of five individuals who were traumatised by the terror attacks of 9/11 starts showing in New York on Wednesday.
It's just one of several films which have attempted to capture the horror of both the day and its aftermath.
Ten years on, Talking Movies' Tom Brook has been looking at the impact of 9/11 on Hollywood.
Talking Movies is broadcast on BBC World News on Saturday at 1330 GMT and is repeated on Sunday at 0030, 0730 and 2030 GMT.
