Keanu Reeves will star in a TV adaptation of “The Devil in the White City,” 

the bestselling nonfiction thriller about ambition, a killer and the 1893 World's Fair in Chicago.

The other central role, that of convicted murderer Dr. H.H. Holmes, has yet to be cast, the streaming service said.

Erik Larson's novelistic-style account of the fair — formally called the World's Columbian Exposition — was published in 2003. 

The fair’s nickname was White City, stemming from the color of many of its building exteriors.

Various Hollywood players circled the book, and Leonardo DiCaprio acquired the rights in 2010, 

with the aim of starring in a big-screen version as Holmes. Martin Scorsese reportedly was set to direct.

Reeves has worked almost exclusively in films, including the “Matrix” and “John Wick” franchises. 

Holmes, born Herman Webster Mudgett, was linked to and confessed to a number of murders.

He was convicted and sentenced to death for only one and was executed in 1896.
