Dakota Fanning is the NYPD's feisty lone female in lush new drama The Alienist, set in 1896 and based on Caleb Carr's 1994 novel. After the discovery of a gruesomely murdered boy, the cops allow an unconventional investigation featuring the pioneering psychologist of the title (Daniel Brühl) in what's essentially a standard "mavericks track a maniac" serial-killer story with period trappings.
Former child star Fanning and German veteran Brühl lead a strong line-up which also features Luke Evans and Brian Geraghty.
