Context: The winners were announced during the awards ceremony on February 26, 2017. Moonlight became the first film with an all-black cast and the first LGBT-themed film to win Best Picture. In an event unprecedented in the history of the Oscars, La La Land was incorrectly announced as the Best Picture, and, a few minutes later, the error was corrected and Moonlight was declared the winner. O.J.: Made in America, at 467 minutes, became the longest film to win an Academy Award, surpassing the 431-minute long War and Peace, which won the Academy Award for Best Foreign Language Film in 1969. Following the five-part documentary's win, new academy rules barred any "multi-part or limited series" from being eligible for documentary categories. With Casey Affleck winning the Oscar for Best Actor, he and his older brother, Ben Affleck, became the 16th pair of siblings to win Academy Awards. Mahershala Ali became the first Muslim actor to win an Oscar. Viola Davis became the first black person to achieve the Triple Crown of Acting with her Oscar, Emmy, and Tony wins.


Question: How many parts did O.J.: Made in America have, and could a documentary with the same length win an Oscar today?


assistant
O.J.: Made in America had 5 parts. Today, documentaries cannot be multi part, so a 5 part documentary could no longer win an Oscar.
