While at Oxford University, Ryder befriends the aristocratic Sebastian Flyte — the 'half-heathen', teddy‑bear-loving son of a Catholic family who reside at a baroque stately home called Brideshead.

Andrew Garfield, will take the part of anguished artist Charles Ryder, the character played by Jeremy Irons in the classic 1981 ITV series.

Joe Alwyn — wearer of the best-looking wigs in The Favourite — will be Sebastian (a role taken by Anthony Andrews in 1981), while his sister, Lady Julia — who comes between his friendship with Ryder — will be played by Rooney Mara.

Ralph Fiennes, who worked with Guadagnino on his hedonistic film A Bigger Splash, has been chosen to play the Flyte siblings' patriarch, Lord Marchmain.

Cate Blanchett is in negotiations to play their pious mother, Lady Marchmain.

Other roles are being cast now for the sumptuous mini-series, which will start filming in the spring at locations in the UK and Venice.
