Following the common BBC practice at the time, shots on sound stages (including those of the "secret garden" itself) were made on videotape while exterior shots were made on film and converted to videotape. In the final video, those shots converted from film fail to be as crisp and clear as the shots made directly to videotape.
In the seventh episode, at 23:11 minutes, as Mr. Craven stops by the Sowerby house and speaks to the kids on his way home, Emma Chambers, the sadly late actress who played Alice Tinker in The Vicar of Dibley (1994) can be seen in an uncredited role as one of the Sowerby children.
The drama was nominated for a British Academy Television Award in 1976 in the drama/entertainment category, and in 1979 it was nominated in the children's entertainment series category at the 1979 Daytime Emmy Awards.
The Secret Garden (1975) is a 1975 British television adaptation of Frances Hodgson Burnett's 1911 novel of the same name. Adapted, produced and directed by Dorothea Brooking, it was first broadcast on BBC 1 in seven 30-minute episodes. This is the only BBC adaptation of the novel known to exist in its entirety. The 1952 adaptation is missing all eight episodes and the 1960 adaptation is missing three of its eight episodes.
