Joseph Mawle (Harry Harville) and Tobias Menzies (William Elliot) would later go on to play the parts of Benjen Stark and Edmure Tully in HBO's Game of Thrones (2011). Their respective on-screen siblings Eddard and Catelyn were married.
The sheer, dotted muslin gown worn by Jennifer Higham (Louisa Musgrove) at Uppercross is the same gown previously worn by Kate Winslet (Marianne Dashwood) in Sense and Sensibility (1995) during the lawn bowling scene at Barton Park, and by Amelia Warner (Fanny Price, age 17) in Mansfield Park (1999). The same costume was later worn by Charity Wakefield (Marianne Dashwood) in Sense & Sensibility (2008) at Norland Park.
Persuasion was one of three novels adapted for ITV's Jane Austen Season. It was the first of the three adaptations to begin development. The drama was co-produced by Clerkenwell Films and American studio WGBH Boston. Persuasion was the third of the Austen adaptations to be shown in the UK and premiered on April 1, 2007 in the United Kingdom and was watched by 5.4 million viewers. Persuasion received positive reviews from television critics.
The role was Rupert Penry-Jones' first lead part in a costume drama. He remarked, "In modern drama everything is so overt. In period drama it's all held in. You have to find ways to show the feelings straining beneath the surface." The actor added that he enjoyed playing Wentworth "because, beyond his social grace and charm, there's a bitterness and sadness because the love of his life, Anne Elliot, rejected him."
The green striped gown with velvet Spencer jacket Julia Davis (Elizabeth Elliot) wears at Kellynch Hall is the same costume Anna Chancellor (Caroline Bingley) wears at Netherfield Hall in Pride and Prejudice (1995). However, the bottom portion of the gown, cut on the bias, has been removed for the later film. This gown also appears in Vanity Fair (1998) worn by Vicki Pepperdine (Ann Dobbin) in the park scenes, and by an extra at the London party where Annabella Milbanke meets Byron in Byron (2003). The Spencer also appears, without the striped gown, in Little Dorrit (2008), worn by Emma Pierson as Fanny Dorrit.
