When Hilde tries to pick up the papers the wind had blown away, the pages are obviously blank.
When Hilde introduces David Cameron to his mother-in-law-to-be, he scantily covers himself with a sheet. In front view there's a glimpse of David's flesh-coloured thong though in rear view he is actually naked.
The scene where Hilde is entering the "Selznick International Pictures" is set in 1948 and the "Hollywood"-sign is visible in the background. In 1948 the sign should have said "Hollywoodland". The "LAND"-part has been deleted in 1949.
