In an article from The Detroit News that mainly talks about the State of Michigan and the incentive money they use to lure film productions to that state, there is this information (below) about a novel called "Crooked Tree" that is to be made into a film set in Michigan.  It doesn't say whether Johnny is interested in the project as a producer, an actor, or both.  We'll just have to wait and see if this is just another rumor, or if something actually comes of it someday.

Northville resident Robert C. Wilson, author of the best-selling novel "Crooked Tree," wants to make his suspense thriller set in northern Michigan into a $17 million motion picture. Director Chris Eyre and actor Johnny Depp are interested, he said.

Wilson said his project and Lake Effect Cinema, which will set up shop at Raleigh Michigan Studios in Pontiac, meet the new criteria the state is considering when reviewing applications.

The state is putting more weight on a project's benefit to Michigan economically, such as ensuring the financial viability of a production company and using existing studios, and showing Michigan in a positive light.

"Every single one of those criteria fits like a glove," Wilson said. "The profits will come back to a Michigan company and be taxed to a Michigan company."

"Crooked Tree" scenes would be shot along the Au Sable River, at Sleeping Bear Dunes, on the Mackinac Bridge and in Petoskey and Charlevoix, he said.

"In terms of showing off the state, it is a veritable Pure Michigan ad campaign," Wilson said.

Michigan's application review committee will meet again next week to go through applications, Jones said. The committee is evaluating every project, no matter the size of the request.
