Duart Castle or Caisteal Dhubhairt in Scottish Gaelic is a castle on the Isle of Mull, off the west coast of Scotland, within the council area of Argyll and Bute. The castle dates back to the 13th century and is the seat of Clan MacLean. The castle was used as a location in the 1999 film Entrapment, starring Sean Connery (who has MacLean ancestry on his mother's side) and Catherine Zeta-Jones. The castle also features prominently in the 1971 film When Eight Bells Toll, starring Anthony Hopkins. It is also the setting for the base of Buffy Summers in the first half of Buffy the Vampire Slayer Season Eight.
