The 1980 film "The Mirror Crack'd" was primarily filmed in Kent, England, with several specific locations used to represent the fictional village of St Mary Mead. Key filming locations included:

• Shoreham, Kent, which doubled as part of the village
• St. Clere Estate in Heaverham, Kent, serving as Gossington Hall, the grand home in the story
• The village of Smarden in Kent, including its traditional thatched houses and shops, representing Miss Marple's village and home
• Ye Olde George Inn and a bridge on Church Street in Shoreham also featured as part of the village scenes

Additionally, some scenes were filmed at Twickenham Film Studios in Twickenham, London. The filming occurred on a roughly 10-week schedule from May 12 to July 18, 1980.
