The company has taken rights to Geraldine McCaughrean's bestseller Stop The Train!, set in the Oklahoma land rush.
Stop The Train! Is the third McCaughrean project on Headline's slate (following on from Peter Pan In Scarlet and Kite Rider.)
Headline is also expected shortly to confirm the director of Alec & May, the US-set drama on which it is partnering with the Weinstein Company. This is about the romance between Scottish inventor Alexander Graham Bell and a 16-year-old deaf girl.
Other titles on Headline's current film slate include Endless Steppe, which Sarah Gavron will direct, and The Invisible Woman, about the romance between Charles Dickens and Nelly Ternan, which Abi Morgan is scripting.
