Anastasia (1956 movie)
While the movie hints that Anna was in fact Anastasia, it is now proved beyond a doubt that Anderson was an impostor. With the final resting places of the Romanovs were discovered in 1991 and 2008, all of their bodies have been accounted for. Additionally, DNA tests conducted on the bodies prove that all were members of the Romanov family. Further, DNA testing on a piece of Anderson's intestine that had been saved during an operation she had during the early 1980s proved that she was not a Romanov, but most likely Franziska Schanzkowska, a Polish factory worker with a history of mental illness. Nevertheless, doubt still persisted. Several strands of her hair were discovered in a book, which was also tested. This too proved she was not a member of the royal family and also increased the likelihood that she was Schanzkowska.
