Hildur Guðnadóttir was awarded the trophy for Best Original Score at the Golden Globes on 5 January, beating other nominees Randy Newman for Marriage Story, Alexandre Desplat for Little Women, Thomas Newman for 1917 and Daniel Pemberton for Motherless Brooklyn. The first female solo winner in the category, she was awarded the prize for her work on Todd Phillips's Joker. It also made her the first woman to win the award since 2000 when Lisa Gerrard and Han Zimmer took it for their work on Gladiator.

The subject of an Invisible Jukebox in the Rewind 2019 issue of The Wire, Guðnadóttir was a member of the group múm. She went on to study electroacoustic composition and has since worked with a number of musicians including Throbbing Gristle, Jessika Kenney and the late Jóhann Jóhannsson. She's produced scores for directors such as Alejandro G Iñárritu and Dennis Villeneuve, as well as for Craig Mazin for his Grammy nominated series Chernobyl.

In her acceptance speech she thanked Phillips for inviting her on a journey of a lifetime.
