Her co-stars, Greg Kinnear and Alan Arkin, both mentioned that they were “astounded by her seriousness of purpose during shooting”. For her performance, Breslin received a Screen Actors Guild Award Nomination, as well as an Academy Award nomination for Best Supporting Actress. At the time of her nomination and at the age of ten years old, Breslin became the fourth youngest actress to be nominated for the Academy Award for Best Supporting Actress. The three actresses younger than Breslin to receive the nomination were Tatum O’Neal, Mary Badham, and Quinn Cummings. Breslin’s co-star, Alan Arkin, did not want her to win the award, specifying that he thought that she has “had enough attention” and “needs to have a childhood”.
