The corridor leading to Colin's room and the interior of the room are decorated with tapestries depicting Edward VI, a sickly boy king who died young at the age of 16.

The tapestries in Mary's room comprise a cycle known as "The Hunt for the Unicorn". In this cycle, the Unicorn is lured from the wild and into a new life by a young virgin, foreshadowing Mary's role in the story.

Portions of several structures were used to depict Misselthwaite Manor. The exterior is primarily 16th-century Fountains Hall in Yorkshire and some of Allerton House in Yorkshire. The kitchen set was built in a classroom at Eton College. Lord Craven's study is at Harrow School. The main staircase was in St. Pancras Chambers, adjoining the busy St. Pancras Station in Central London. The bedroom interiors were shot on sets on 'A' stage at Pinewood Studios. The grounds were shot in Allerton Park in North Yorkshire and some of Luton Hoo in Hertfordshire as well as Pinewood Studios in Buckinghamshire. The topiary arch used for the Misselthwaite garden leads directly onto Conistone Moor in North Yorkshire.

In Burnett's book The Secret Garden it is Mary's father who is related to Colin's mother. Also they were not twins.
