The cast of 'Sex and the City: The Movie' had to work extra hard on a 19-hour shoot at Christie's auction house.

Pagesix.com reports that an insider said: 'Christie's would only give them one day to shoot.' The cast and the crew had to show up at 7 a.m. to shoot double the number of scenes that were normally supposed to be shot and had to stay on till midnight.

The insider added: 'The production company issued a second meal, which is very rare and were paid overtime. Sarah Jessica Parker worked so hard and was just wonderful to everyone involved.'
