Martin Scorsese says next film with Leonardo DiCaprio will be 'Devil in the White City'

“Right now, there is a script being worked on,” Scorsese said of an adaptation of Erik Larson’s book, The Devil in the White City: Murder, Magic, and Madness at the Fair that Changed America. Larson’s tale, based on a true story, entwines the stories of a notorious serial killer and the architect who designed the 1893 World’s Fair in Chicago.
“One of the things that I had to stop for the past six months,” Scorsese said about his final push to complete his new spiritual drama Silence, “was my meetings on that script. They want me to start again in January and see if we can find a way because it’s an extraordinary story.”
DiCaprio purchased the film rights in 2010. Scorsese said he looks forward to working again with DiCaprio, as they have on past films such as Gangs of New York, The Aviator, The Departed, Shutter Island and The Wolf of Wall Street. They share a vision on film and on life, he explained. “We’ve become very close and we really love hanging out together.”

It might not be as great a collaboration as De Niro/Scorsese, but Dicaprio/Scorsese is as great a director/actor collaborative as we have these days at the cinema. I'm looking forward to this next chapter and do believe that what they have built over these last 16 years is something very special. 

Right now, I'd rank the Scorsese/Dicaprio's like this:

1) The Departed
2) The Wolf of Wall Street
3) The Aviator
4) Shutter Island
5) Gangs of New York
