This year, as the Tribeca Film Festival marks its 20th anniversary, it also marks nearly 20 years since the terror attacks at the World Trade Center on September 11, 2001.

A six-part series called "9/11: One Day in America," takes an in-depth look at that fateful day in New York City. It’s the first series to be produced in partnership with the 9/11 Memorial & Museum. Director Daniel Bogado said the archivist there played a huge role in re-telling the story.

What You Need To Know

  • A six-part series documenting the events of 9/11 and its immediate aftermath is now playing the Tribeca At Home portion of the annual Tribeca Film Festival 

  • The series is being produced by National Geographic, which will air all six parts later this year 

  • The entry has a direct connection to the roots of the Tribeca Film Festival, which was started as a way to attract more visitors to downtown Manhattan following the 2001 attack on the World Trade Center

“We developed a very close relationship with the archive team of the museum, because they're just the center for the study of this," said Bogado. "They have the most extraordinary and immense collection of all these things.”

Bogado said they provided him with amazing video, photographs and voicemails.

"In a way the museum itself and the memorial, it was a source of inspiration to us," he said.

Bogado hopes that the series creates a legacy for the next generation.

“Somebody who was not born, was not alive at that time, they're never going to experience what it was like being alive at that time, and either watching the images on your TV screen or being at the site or near the site of the tragedy,” said the series director.

"9/11: One Day in America" is streaming now on Tribeca At Home. it will also debut later this year on National Geographic.
