Maris' screen debut was in the German film "Los Esclavos del Volga", directed by Richard Eichberg. (The book "Hollywood—Se Habla Español" says, "Maris' film career began with the 1925 silent movie "The Apache"", while a 1985 Associated Press newspaper article wrote "She first appeared in the British-made movie, "The Little People" in 1924.") Jorge Finkielman wrote about her performance in his book, "The Film Industry in Argentina: An Illustrated Cultural History": "Her portrayal of the character Tatiana showed that she was an actress who could be expected to turn out noteworthy performances."
