The kitchen scene near the beginning of Episode One was filmed three separate times as none of the actors were available on the same day to film. They all had to read their lines whilst pretending the others were present.
Main filming for the SEnder began on 24th July 2018. The scene in Episode Two where Brooke and Mila talk to Nathan at the café was the last scene to be filmed on November 2nd 2018, just two days before the series premiere.
When filming the shot at the end of Episode Three where the camera pans around the table, the actors struggled to keep straight faces. In the end it took a total of 12 attempts.
The scenes in Jack's living room at the beginning of Episode One were all filmed separately on different days. Harry and Lottie on one day, Grace and Nat on another and finally Lydia. In fact, most of Episode One had to be filmed in this way due to actors being unavailable for shooting dates.
Episode Four was all filmed in one sitting. The actors completed it in a total of 3 hours, wrapping filming at 10PM.
