There was disappointment for Saoirse Ronan at the Oscars in Hollywood on Sunday night, with the Lady Bird star losing out on the Best Actress award to Three Billboards Outside Ebbing, Missouri star Frances McDormand.
It was Ronan's third Oscar nomination and McDormand's second win - she previously won for Fargo. Lady Bird, which was nominated in five categories, went home empty-handed on the night.
The Shape of Water was the biggest winner on the night, winning Best Picture, Director, Music and Production Design.
The awards show began with a win for McDonagh's film as Sam Rockwell was named Best Supporting Actor.
Accepting his award, Rockwell paid tribute to London-Irish filmmaker McDonagh.
"I wouldn't be standing here if it wasn't for you," said Rockwell. "I want to do ten other movies with you. I love you."
There was disappointment for the Irish animated film The Breadwinner, which lost out on Best Animated Feature to the favourite, Coco.
History was made when James Ivory won Best Adapted Screenplay for Call Me by Your Name - at 89 years of age he is the oldest winner in Oscars history.
In the other acting categories, Gary Oldman was named Best Actor for Darkest Hour with Allison Janney winning Best Supporting Actress for her role in I, Tonya. Like McDormand and Rockwell, Oldman and Janney had been the favourites in their respective categories.
You can watch the Oscars on RTÉ2 on Monday night at 9.30pm.
