Carey Mulligan accidentally announced as best supporting actress instead of Kerry Condon at 2023 BAFTAs

• Carey Mulligan was accidentally announced as best supporting actress at the 2023 BAFTAs.
• Deaf actor Troy Kotsur was presenting the category and signed Kerry Condon's name, who won.
• But BAFTA told Insider Mulligan's name was read as a mistake by the sign language interpreter.

Carey Mulligan was accidentally announced as best supporting actress at the 2023 BAFTAs instead of the actual recipient of the award, Kerry Condon.

The mistake was made as the second award of the night was being announced by Troy Kotsur. According to BAFTA representatives, Condon's name was written on the card and while Kotsur signed the Irish actor's name correctly, the sign language interpreter providing voiceover for the audience at London's Royal Festival Hall thought he had signed Mulligan's name instead.

However, before Mulligan — who was in the running for the award for her performance in "She Said" — walked onto the stage, Condon's name was read out and the actors were made aware of this mistake.

Condon took home the coveted award for her performance in "The Banshees of Inisherin." 

The other women up for the running of best supporting actress were Angela Bassett for "Black Panther: Wakanda Forever," Hong Chau, for "The Whale," Dolly De Leon for "Triangle of Sadness," and Jamie Lee Curtis for "Everything Everywhere All At Once."

During her acceptance speech, Condon did not reference the incident. Instead, she paid tribute to the film's director Martin McDonough.

"Thank you for all the parts you gave me throughout my career. You make me so proud to be an Irish woman," Condon said.

When host Richard E. Grant returned to the stage, he joked about having a defibrillator on standby for Mulligan.

Condon's "Banshees of Inisherin" costar Barry Keoughan picked up the award for best supporting actor, while the film also took home best original screenplay as well. 

Insider was told by a BAFTA representative that the moment will not air in the final broadcast on BBC One, which was streaming slightly behind the live ceremony.
