A “sparrow” is the term for a Mata Hari style secret agent, trained to seduce men in pursuit of secrets. Ballerina Dominika Egorova (played by Jennifer Lawrence) is inducted into this life by her uncle Vanya (I know, I know; the Chekov references could be subtler), a spymaster, when her ballet career is cut short by a serious injury. Trained at spy school by the cynical Matron (Charlotte Rampling) and directed by General Korchnoi (Jeremy Irons), Dominika is soon thrust into the cut and thrust world of espionage.
The best thing about this movie is the opening scene. We meet Hercule Poirot and his unique personality, and moustache in the middle of avoiding a religious war at Jerusalem’s Wailing Wall, and things are off to a great start. The story flows and so does the action, and before we know it, we find ourselves along with Poirot on the Orient Express from Istanbul to London.
