They were filming at Ascot Racecourse from 9 am to around 12 pm ( if I remember correctly), so it's plausible that they've filmed more scenes there,not only the ones set at Shanghai International Airport which were night shots.Interesting. Ascot appears to be in the film both as Royal Ascot and as Shanghai airport. Unless this is jsut the cameras being set up before the set is re-decorated.
Plus, consider the fact that as far as we know not only chinese extras were involved in the shooting at Ascot Racecourse.
