Touchstone Pictures has acquired The Lighthouse, a claustrophobic thriller by Dean DeBlois that will be produced by Andrew Gunn and his Gunn Films banner, says The Hollywood Reporter.

The story is set off the coast of Brittany in the English Channel, where lighthouses perch on solitary pieces of rock and lighthouse keepers live in isolation for two months at a time. When a man arrives to one lighthouse to install automated equipment, he meets two brothers who have been living there for years and begins to unravel their dark secrets.

DeBlois was the co-head writer on Mulan and co-wrote and co-directed Lilo & Stitch from the Walt Disney Co.
