Warner Bros. has acquired the John Leake book "
Entering Hades" and has attached Robert Schwentke to direct the adaptation.
The book, published late last year by Farrar, Straus & Giroux, is about Jack Unterweger, a journalist who led a double life strangling prostitutes in Vienna and Los Angeles, and covering his own crimes in the early 1990s. Unterweger hanged himself after receiving a life sentence.
