"Tron: Legacy" star Garrett Hedlund is reportedly in talks for the lead role in "The Alienist," the TNT period thriller from Cary Fukunaga. The news arrives courtesy of TheWrap, which notes that no deal is in place.

Based on Caleb Carr’s bestselling crime novel, the psychological thriller follows psychiatrist Laszlo Kreizler as he joins forces with a newspaper reporter, a police department secretary and Police Commissioner Theodore Roosevelt to stop a serial killer stalking late 19th-century New York City.

TNT ordered "The Alienist" in May, and will reportedly spend about $5 million an episode on the eight-part series.

Hossein Amini ("47 Ronin," "Snow White and the Huntsman") wrote the adaptation, which hails from Paramount Television and Anonymous Content.
