I greatly admire the superb television production of Brideshead Revisited, that I first watched on a 19-inch black & white TV when it originally aired in 1981. Brideshead is as far from British Kitchen Sink Realism as it gets, this side of Shakespeare.
The series was co-directed by Michael Lindsay-Hogg, whose name was heard often a year ago when Disney released The Beatles: Get Back. Lindsay-Hogg directed Let It Be, and his original reels of film were used by Peter Jackson for his project.
The complete Brideshead series is here, although the playlist has the eleven episodes out of order. I’ll leave it to you to sort them out from the drop-down menu.
