The white floral and polka dot day dress Freema Agyeman (Tattycoram) wears bowling with Pet Meagles is the same costume Samantha Morton (Harriet Smith) wears on the horse with Frank Churchill in _Emma (1996)(TV)_.
The tan striped gown with teal scallop trim at the hem Emma Pierson (Fanny Dorrit) wears to visit Mrs. Merdles is the same costume Greta Scacchi (Mrs. Weston) wears in the final scene of Emma. The same costume is also worn by a guest at the Easter Ball in "Wives and Daughters" (1999).
The tan velvet hat worn by Maxine Peake (Miss Wade) is the same hat Marsha Fitzalan (Caroline Bingley) wears in the coach with Mr. Bingley in "Pride and Prejudice" (1980).
The gold overdress worn by one of the dancers leaving the theatre while Amy waits for Fanny is the same costume Juliet Stevenson (Mrs. Elton) wears at the Box Hill picnic in Emma. The costume is also worn by a guest at the London party where Byron meets Annabella Milbanke in Byron (2003) (TV).
The shear ivory gown with pink satin ribbon rosettes worn by Ruth Jones (Flora Finching) is the same costume worn by Geraldine James (Lady Emma Hamilton) in "I Remember Nelson" (1982).
The tune Rigaud (Andy Serkis) often sings is called "Le Chevalier du Guet", also known as "Les compagnons de la Marjolaine".
When Pancks scans a page of Mr. Chivery's book at the Marshalsea, looking for information on Mr. Dorrit, one can see that the entry directly above William Dorrit's is that of John Dickens. Dickens was the father of Charles Dickens and an inmate of the Marshalsea Debtors' Prison for a few months in the 1820s. Besides the imprisonment date, John Dickens' year of birth was also altered.
In the scene where Amy is working at Mrs. Clennam's house, the embroidery that Amy is working on reads 'Istanbul Yadegari' in old Turkish, literally meaning 'a souvenir from Istanbul'.
The normal Thursday showing of this episode (on 4 December 2008) was cancelled to make way for a last-minute programme about Karen Matthews who had just been convicted of kidnapping her daughter Shannon. Consequently the episode was first shown in the omnibus edition on the following Sunday.
