The red gown with brocade bodice and capped sleeves Sophie Thompson (Mary Musgrove) wears to dinner at Uppercross is the same gown Sylvestra Le Touzel (Mrs. Allen) wears in Bath in Northanger Abbey (2007).
The white and red print muslin wrap-style day dress Sophie Thompson (Mary Musgrove) wears at Barton Cottage is the same costume Rosamund Pike (Jane Bennet) wears at Longbourn in Pride & Prejudice (2005).
The brocade suit Corin Redgrave wears during the scene in which Sir Walter Elliot tries to induce Anne to accompany him to Lady Dalrymple's is the same costume James D'Arcy (Tom Bertram) wears during the play rehearsal in Mansfield Park (2007).
While clearing out her things at Kellynch near the beginning of the film, Anne finds a paper boat tucked inside a navy list. If you look closely, you can see that the words written on it come from the letter Captain Wentworth writes to her at the end of the film. It says: "You pierce my soul. I am half agony, half hope. Tell me not that such precious feelings are gone for ever. I offer myself to you again..."
When Captain Harville and Anne Elliot discuss whether men or women are the most inconstant in love the camera continues to switch between a closer shot of the two and a more distant shot to include Captain Wentworth. In one of the more distant shots (while Captain Harville discusses the feeling of leaving behind family) you can see Anne is the one speaking however Captain Harville's voice is heard.
