There's no question as to what the biggest arrival on Prime Video UK this month will be. The Lord of the Rings: The Rings of Power, set centuries before the main Lord of the Rings series, is the most expensive TV show of all time and a huge investment for the streaming service behind it. Led by Morfydd Clark as Galadriel, it explores the forging of the titular rings and the rise of the evil Sauron.

The Lord of the Rings: The Rings of Power S1 (weekly from 2 September)

Saint Maud star Morfydd Clark leads the cast as Galadriel, with Robert Aramayo portraying Elrond.
