There's been another new cast announcement for Netflix's second-last season about the Royal Family.

'The Crown' season five has found its young Prince William, and the likeness between father and son on the Netflix adaptation is about to reach a whole new level of similarity.

Following a nationwide search for a young actor to play the role, Dominic West's son Senan West has been chosen. The 13-year-old will join his father in the series, who was previously cast as Prince Charles in his later years for seasons five and six, following Josh O’Conner's performance.

Although an acting newcomer, Senan West's audition tape caught the attention of the show's producers, according to Variety. He is expected to appear in the latter half of season five, playing a slightly older Prince William. With the next season set during the '90s, it seems extremely likely that the tragic death of Princess Diana in 1997 will unfold, or at least the moments leading up to it. William was aged 15 when the incident took place.

Joining both Dominic and Senan West in season five of 'The Crown' is Imelda Staunton, who takes over from Olivia Colman as Queen Elizabeth II.

Princess Diana will be played by Elizabeth Debicki, taking over from season four's Emma Corrin. Khalid Abdalla will star as Diana's romantic link during this time, Egyptian film producer Dodi Al Fayed. Both died in a car crash in Paris on August 31, 1997.

Jonathan Pryce will play Prince Philip, replacing Tobias Menzies, while Helena Bonham Carter has been swapped out with Lesley Manville as Princess Margaret. Jonny Lee Miller will also appear as Prime Minister John Major.

'The Crown' season five will premiere on Netflix in November, 2022.
