From the (Glasgow) Herald:

GLASGOW's lord provost, Liz Cameron, is hoping that the annual conference of the Association of Film Commissioners International coming to Glasgow will mean even more films being shot in the city. She named House of Mirth, based on Edith Wharton's Victorian novel, as her favourite movie filmed in Glasgow.
"Glasgow became nineteenth-century New York," recalled Liz, whose City Chambers office was transformed into a New York hotel bedroom. "Nothing saucy happened," she assures us. "Edith Wharton stories aren't like that … and I wasn't there."
