Spy thriller “Target Churchill” is in development as a movie with Grey Eagle Films and sales-financing company The Solution Entertainment Group.

“Target Churchill,” written by Warren Adler (“The War of the Roses”) and Churchill biographer James C. Humes, centers on a fictionalized Soviet conspiracy to assassinate Churchill in order to prevent him from delivering his “Iron Curtain” speech in Fulton, Mo., in 1946. The assassin is a Russian mole and Nazi who served in Hitler’s SS and is now living in the United States.

Adler has written the adaptation.

Grey Eagle is teamed with Permut Presentations on developing Adler’s “War of the Roses: The Children” as a sequel to the 1989 Michael Douglas-Kathleen Turner black comedy.

Grey Eagle was founded by Jonathan Robert Adler and veteran film executive Stephen Greenwald, former President of De Laurentis Entertainment Group and Embassy Pictures. It has obtained the film and TV rights to Warren Adler’s entire body of works.

Adler’s Fiona Fitzgerald mystery series is in development as a TV series with Sennet Entertainment. Eric Overmyer is the showrunner.

The Solution’s current slate includes Lynn Shelton’s “Laggies,” “Infinitely Polar Bear starring Mark Ruffalo and Zoe Saldana, “Ten Thousand Saints” and “Bleed For This,” starring Miles Teller and Aaron Eckhart.
