Shooting the Past (1999)

Past and present collide when a London mansion housing a monumental collection of photographs is purchased by an American entrepreneur intent on turning the building into a business school. Determined to clear the house of its prized contents, the millionaire (played by Liam Cunningham) finds he's met his match in the house staff (including Lindsay Duncan as the house manager), who are hell-bent on preserving the archives at all costs.
