Eva Nill, stage name of Eva Comello (Cairo, June 25, 1909 – Cataguases, August 15, 1990), was a Brazilian film actress. Daughter of the Italian Pietro Comello and sister of the actor Ben Nill (Roger Comello), Eva was one of the favorite actresses of filmmaker Humberto Mauro, during the film cycle in Cataguases. She participated in the feature films Valadião, o Cratera (1925) by Humberto Mauro; Na Primavera da Vida (1926), directed by Humberto Mauro; Senhorita Agora Mesmo (1928), directed by Pedro Comello and Barro Humano (1929), directed by Adhemar Gonzaga, now lost, with only photographs remaining. Her face was featured on the cover of Cinearte magazine twice, which helped solidify her fame and create the myth, with many calling her "The Brazilian Greta Garbo". Having prematurely abandoned cinema in the late 1920s, she began working as a photographer in Cataguases, alongside her father. Unmarried, she died in 1990, at the age of 81, in Cataguases.
