Olga, Tatiana and Maria were the older sisters of Anastasia. They were killed during the assassination of the
Romanov family. They are minor characters in the Anastasia film.
Like Anastasia; Olga, Tatiana, and Maria shared the same traits: fair skin, auburn hair, thick eyebrows and light blue Romanov eyes with naturally groomed eyelashes. The only difference out of the girls are that all three shared different hairstyles: Olga has a ponytail, Tatiana's hair is shorter and cut in an elegant way and Maria has her hair tied at sides and lay over her shoulders. It's interesting to mention that Maria's hair color is the brightest one compared to her sisters, while Olga's and Tatiana's hair color are not as red as Anastasia's one. However, Tatiana's hair color is darker than Olga's. Also, in the movie is seen that Tatiana stands out from Olga and Maria for being the tallest one (as seen in the final scene of Once Upon a December).
Their personalities are not well defined since they rarely appeared in the movie and hardly spoke. However, in the scene in which all the three surrounded Anastasia during Once Upon a December, we can see they were fond of their sister, Anastasia , since they came to her (as if they wanted to greet), and stood a moment with her (before they were taken out to dance). At the time they were with Anastasia, they were happily surrounding her, meanwhile, Maria gave her a pearl necklace, indicating as if she would have wanted to join Anastasia to the ball with them. Later on, they're seen in Anastasia's dream (later nightmare). Even though it's known that the dream was just one of Rasputin's traps in order to kill Anastasia, we can analyze that Olga, Tatiana, and Maria were once playful with each other, since they were waving happily to Anastasia, before they'd jump to the pool with their father. Further in the film, we could tell that Olga was a teaser person as told by Anastasia to Marie, since she criticized Anastasia's old drawing by saying that it looked like a pig riding a donkey (which in real life, she did say that, but to their father).
