Irish animation Wolfwalkers from Kilkenny's Cartoon Saloon has missed out on the Animated Film BAFTA to Pixar's Soul, while Calm With Horses star Niamh Algar missed out on the Best Supporting Actress gong to Yuh-Jung Youn for her role in Minari.
Algar's co-star Barry Keoghan also lost out to Daniel Kaluuya in the Best Supporting Actor award for this role in Judas and the Black Messiah.
Calm with Horses, which was shot in Galway and Clare and was up for four awards, was also beaten in the nominations for Best British Film to Promising Young Woman, and Best Casting by Rocks.
Controversial revenge drama Promising Young Woman, which is the directorial debut of The Crown actress Emerald Fennell, stars Carey Mulligan as a woman left traumatised by tragedy.
Fennell joked that everyone made the film for "a packet of crisps" and said the experience was "the greatest thing in my life."
A handful of presenters were in attendance at this year's BAFTA ceremony, with winners and nominees accepting their awards virtually.
The ceremony, which was hosted by Edith Bowman and Dermot O’Leary, followed on from Saturday night’s ceremony – which saw behind-the-camera categories, including casting and make-up, winners announced.
Britain's Duke of Cambridge, who is the current president of BAFTA, was to feature virtually in this year’s awards, but pulled out following the death of his grandfather, the Duke of Edinburgh, on Friday.
TV presenters Bowman and O'Leary paid tribute to Britain's Prince Philip following his death aged 99, with Bowman saying Philip "occupies a special place in Bafta history and our thoughts are with the royal family".
