9pm, Sky Documentaries
Buckle up for this one: a wild new documentary series from the US that has been described as “Succession meets Game of Thrones”, follows Texas Renaissance festival co-founder George Coulam, who, now in his 80s and ideally wanting to die “by being screwed to death”, is looking for his heir. Some colourful characters enter the ring, as we learn the backstory of this absurd world, in which he has become known as the “king”. Hollie Richardson
