While season 5 now has its Margaret, Netflix has yet to announce who will be taking over the role of Philip in that final season.
The 64-year-old will take over the role in the series' fifth season, which is expected to be released late next year.
Season three of The Crown took place during 1964 and 1972 and is covering major events in British history, like Princess Margaret's affair with Roddy Llewellyn, Margaret Thatcher's political rise, and the introduction of Camilla Parker Bowles. As the story unfolded over the years, we watched the consequences of standing in her sister's shadow manifest in heartache, disappointment, and disdain. The princess suffered several strokes before passing away in 2002.
The Harry Potter actress, Imelda Staunton is one of the most experienced and nuanced actors from the Hollywood industry, and it will be exciting to see Lesley Manville join the cast.
Lesley is an award-winning actress who has appeared across television, film and theatre.
"I could not be happier to be playing Princess Margaret", the British actress said in the announcement.
The upcoming season of "The Crown" will tackle the 1980s for the famous royal family and it will also introduce new characters, including Princess Diana played by Emma Corrin. You're going to need the refresher by the time season five finally drops.
