The third Knives Out movie, titled Wake Up Dead Man: A Knives Out Mystery , was filmed mainly in and around London and the southeast of England, with a few extra shots done in upstate New York.

Main filming locations

  • The bulk of production took place in the UK, using real English countryside to stand in for the fictional American town of Chimney Rock in upstate New York.
  • Key work was done in and around London and nearby counties, with studio work on specially built sets for interiors.

The church and village

  • The striking Neo‑Gothic church exterior is Holy Innocents Church in High Beech, in Epping Forest, Essex, just outside London.
  • The graveyard, surrounding lanes, and forest paths you see around the church were all shot on location in Epping Forest, doubling for small‑town upstate New York.

Other UK spots used

  • Interior church scenes were recreated on custom sets at Leavesden Studios in Hertfordshire, a major UK film studio complex.
  • Additional countryside and estate scenes were filmed in Surrey, including Winterfold Forest and a private home near Guildford used as one character’s estate.

Actual US shots

  • While the town is fictional, there are brief establishing shots filmed in the real village of Cold Spring, New York, in the Hudson Valley, used to sell the setting as upstate New York.
  • Local reports mention filming around Main Street and nearby residential blocks in Cold Spring for those quick street and town cutaways.

TL;DR: Wake Up Dead Man: A Knives Out Mystery is set in a made‑up upstate New York town but filmed mostly in the UK (Holy Innocents Church in High Beech/Epping Forest, Surrey locations, and studio sets at Leavesden), with a sprinkling of real upstate New York shots in Cold Spring for authenticity.
