There were many parallels between this year's Academy Awards and the Golden Globe Awards.
Frances McDormand won both times as best actress for her performance in Three Billboards Outside Ebbing, Missouri.
And Gary Oldman won both times for best actor for his role in Darkest Hour, in which he played Winston Churchill.
Another double winner was Allison Janney. She was honoured with best actress in a supporting role by the Academy of Motion Picture Arts and Sciences and the Hollywood Foreign Press Association for her blockbuster performance as disgraced skater Tonya Harding's mother in I, Tonya.
Similarly, Sam Rockwell won an Oscar and a Golden Globe for his supporting role in Three Billboards Outside Ebbing, Missouri.
The best director Oscar went to Guillermo del Toro for The Shape of Water, just as it did at the Golden Globes.
And both shows were hosted by late-night white-male comedians on major U.S. networks. Jimmy Kimmel was the ringmaster at the Oscars whereas Seth Meyers steered the ship at the Golden Globes.
But there was a different winner for best picture at the Oscars.
The Shape of Water was chosen by the Academy, whereas Three Billboards came out on top at the Golden Globes.
Alexander Desplat won the Oscar for original score for The Shape of Water, just as he won a Golden Globe award earlier this year.
The Oscar for original song went to "Remember Me" in the film Coco, with music and lyrics by Kristen Anderson-Lopez and Robert Lopez. That didn't win at the Golden Globes, however, as the foreign press went with "This Is Me" from The Greatest Showman.
Other Academy Award winners included:
* Roger A. Deakins for best cinematography for Blade Runner 2049;
* Jordan Peele for best original screenplay for Get Out;
* James Ivory for best adapted screenplay for Call Me By Your Name;
* Blade Runner 2049 for best visual effects (John Nelson, Gerd Nefzer, Paul Lambert, and Richard Hoover);
* The Shape of Water for best production design;
* Coco for best animated feature;
* Icarus for best documentary feature;
* and A Fantastic Woman for best foreign language film.
This year, the Academy invited Ashley Judd, Annabella Sciorra, and Salma Hayek on-stage to introduce a video montage on equality and the importance of diverse representation.
All three have previously gone public with horrific stories of abuse at the hands of producer Harvey Weinstein.
The Academy also honoured activists with a performance of "Stand Up for Something" by Andra Day and Common.
It was preceded by an amusing monologue by comedian Dave Chapelle.
