As the plot of the film, which stars Milla Jovovich, is said to be based on actual events that occurred in Nome Alaska in 2009, the doctor character may well be based on a real life doctor in the town who played a part in the events that are supposed to have taken place in 2000.
The film itself is about a psychologist called Dr Abbey Tyler who uses hypnosis techniques to delve into and recover memories from patients of alien abductions. During some of the supposed abductions some patients speak a strange language and Dr Tyler resorts to calling in a friend of her late husband, Dr Odusami. As an expert in ancient languages, he is reported in the film to have identified it as Sumerian.
