 An early idea of David S. Goyer (qv) was to include not only  Hannibal King, but a female character called Rachel Van Helsing from  the Tomb of Dracula comics, but then he heard about the movie  _Van Helsing (2004)_ (qv) and decided against it. He ended up  creating the character of Abigail Whistler, Whistlers daughter, in  her place.
