Downton Abbey DVD Commentaries → S1E1 (Julian Fellowes, Gareth Neame, and Brian Percival)
Brian: This was the very first scene we ever shot and I think it was around the beginning of March and in that courtyard it was -6 °C that morning.
Gareth: Freezing, wasn’t it?
Brian: Highclere is very, very high and consequently very, very cold.
Julian: Well, of course, you lose the fact that we can see their breath because they’re both smoking!
