Vivien Lyra Blair

[4] While the film itself received mixed reviews,[10] The Daily Telegraph praised Blair's performance as "very funny" and "just absurd ... the effects team simply aren't needed when she's doing her thing".

Harold found Blair to be "an amazing little actor" who miraculously captured that spirit, particularly in her scenes with co-star Ewan McGregor.

[13] Blair was praised for her portrayal of the character's strength, wit, and intelligence;[14] NPR commented that she "practically channels Carrie Fisher's subversive, wisecracking spirit".

[15] In a more mixed review of her performance, Nick Schager of The Daily Beast thought Blair's line deliveries were "not ... consistently great" but considered her adequate for the role.

[17] Blair played Emily Gradstone in the film drama Dear Zoe, which is based on the eponymous young-adult novel by Philip Beard.

[19] In July of that year, Blair joined the cast of the horror film The Boogeyman (2023), an adaptation of Stephen King's eponymous short story.

[22] Several critics lauded her performance;[23][24][25] The Hollywood Reporter stated: "Blair is so convincingly terrified throughout that you hope that child services monitored the production closely".
