The classic British TV serial, starring Jeremy Irons and Anthony Andrews, follows the life and romances of the protagonist Charles Ryder - including his friendship with the Flytes, a family of wealthy English Catholics who lives in a palatial mansion called Brideshead Castle.
According to the Daily Mail's Baz Bamigboye, Garfield will take the part of anguished artist Ryder, previously played by Irons in the 1981 original, who befriends Alwyn's aristocratic Sebastian Flyte while at Oxford University. His sister, Lady Julia - who comes between his friendship with Ryder - will be played by Mara.
Fiennes, meanwhile, has been chosen to play the Flyte siblings' patriarch, Lord Marchmain, with Blanchett in negotiations to play their pious mother, Lady Marchmain, reported the Daily Mail.
Luca Guadagnino, best known for his movie "Call Me by Your Name", will adapt Evelyn Waugh's classic novel as well as direct the multi-part drama for the BBC and HBO. Filming is expected to start in spring, 2021.
Andrew Garfield was last seen on the big screen in 2018's neo-noir black comedy thriller "Under the Silver Lake". His new movie "Mainstream" premiered at the Venice Film Festival on September this year. His next projects include drama "The Eyes of Tammy Faye" and Lin-Manuel Miranda's musical "Tick, Tick... Boom!"
He is also rumored to join the new Spider-Man, Tom Holland, in the upcoming third movie reboot along with another Spidey alum Tobey Maguire as the new film is expected to feature multiverse storyline.
The casting rumors came a few months after it's revealed that the 2018 animated "Spider-Man: Into the Spider-Verse", which revolved around black Spidey Miles Morales, almost brought together the three life-action movie stars Andrew, Tobey, and Tom.
