Miller who played Sick Boy in Danny Boyle's hit movie, based on Irvine Welsh's 1993 novel about a group of Edinburgh junkies, will play former politician Major, who led the U.K. from 1990 to 1997, succeeding Margaret Thatcher as leader of Britain's Conservative government.
Gillian Anderson, who played Major's predecessor Thatcher for season four, won a Golden Globe for her performance.
Miller, 48, will join a refreshed cast which sees Imelda Staunton taking over from Olivia Colman as Queen Elizabeth, Lesley Manville stepping into Helena Bonham Carter's role as Princess Margaret, "The Wire" 's Dominic West replacing Josh O'Connor as Prince Charles, "Widows" star Elizabeth Debicki replacing Emma Corrin's Princess Diana, and Jonathan Pryce taking over from Tobias Menzies as Prince Philip.
The fifth series, will reportedly begin filming in July (21), and will focus on another difficult decade for the royals, with a string of splits and scandals and the death of Princess Diana.
The news was announced on the show's Twitter account on Friday (25Jun21).
The fourth season, airing last year, sparked new criticisms against Prince Charles over his treatment of Princess Diana. British's Culture secretary Oliver Dowden even pressured Netflix to add fiction disclaimer, but the streamer refused.
"We have every confidence our members understand it's a work of fiction that's broadly based on historical events," the company explained.
