While we've all heard the immortal words of Neil Armstrong, who declared his first steps on the moon to be "one small step for [a] man, one giant leap for mankind," a new documentary aims to give newfound clarity to the 1969 moon landing.

Director Todd Douglas Miller's new film, Apollo 11, just premiered at the Sundance Film Festival last week, and the official trailer is now available online. You can check it out right here.

Apollo 11 was compiled using some previously unseen 65mm footage that was discovered in the National Archives, along with 11,000 hours of uncatalogued NASA audio recordings. The unprocessed footage was then digitized, and it revealed an unprecedented look at the Herculean task of sending astronauts to the moon, then returning them safely to Earth.

Despite being 50-plus years old, Miller says it's "the highest-quality digital collection of Apollo 11 footage in existence." When all spliced together, he uses Apollo 11 to tell the story of NASA's most celebrated mission from the point of view of the astronauts, Mission Control, and the countless individuals who watched in awe from the ground as the event unfolded.

The film was acquired by NEON in 2018, and was announced on the 49th anniversary of the moon landing last summer. It marks the second collaboration between the indie distributor and CNN Films. The two worked together last year on the riveting documentary Three Identical Strangers.

There's no official release date for Apollo 11, but given that the 50-year anniversary of the moon landing is coming up this summer, it's possible it could land in theaters somewhere around then.
