Any viewers of The Crown will know that show can contain some rather gloomy subject matter but that atmosphere doesn't seem to have affected the cast's day-to-day mood.
We've already seen some behind the scenes footage of Olivia Colman (Queen Elizabeth) and Emma Corrin (Diana Spencer) having the chats as well as Gillian Anderson (Margaret Thatcher)'s phone clips of the cast having a right old sing-song.
It was Anderson who was presented with arguably the best unseen The Crown footage of all when she appeared on Late Night with Seth Meyers earlier this week.
During a virtual interview, the host brought up the subject of a video clip which features members of the cast performing a choreographed dance to Lizzo's hit Good As Hell. Anderson explained that it all stemmed from a dance class that Olivia Colman was undertaking with some friends of hers. Colman thought it would be fun to have her co-stars try it out and, well, the results are spectacular.
You can watch it below from around the 2 minute 30 mark...
Like they're all amazing but particular props to Tobias Menzies (Prince Philip) who seems to be having the time of his life.
We're very much looking forward to the next season of The Crown, for the behind the scenes antics as much as anything else.
