In her book "The Sense and Sensibility Screenplay & Diaries: Bringing Jane Austen's Novel to Film", Emma Thompson writes that after a particularly difficult day filming a sequence that involved a flock of sheep, Ang Lee swore that he would never again use the animals on a movie set. Ten years later, however, Ang Lee went on to direct (and win a directing Oscar for) Brokeback Mountain (2005), which is about two men who meet while sheep herding.
Originally, there was to be a scene in which Hugh Grant would kiss Emma Thompson. This scene was deleted, however, because the film was too long already. They deleted another scene too because of the length.
Emma Thompson has recounted how during the scene where Colonel Brandon, on horseback, approaches Elinor and Marianne in the out-of-doors, many takes were ruined by the horse surrendering to a bout of flatulence. Eventually, they were forced to shoot the scene with the farting horse as the flatulence would not abate, and the rather loud reports later were edited out of the soundtrack.
During filming, the Jane Austen Society telephoned co-producer James Schamus to complain about the casting of Hugh Grant claiming that he was too good-looking to play Edward Ferrars.
The Dashwoods moved to their humble cottage when the weather was cold and the sheep still had their long, winter coats. The scenes were in fact filmed in late May, and in one take a sheep keeled over from heat exhaustion. So the sheep were immediately sheared and later appear with their haircuts, despite the wintry setting.
Emma Thompson's first draft of the screenplay consisted of 350 hand-written pages. The final draft was a culmination of that and 13 other drafts which were written over four and a half years.
Marianne Dashwood's wedding dress was trimmed with straw.
The sheer dotted muslin gown Kate Winslet, (Marianne Dashwood), wears during the lawn bowling scene at Barton Park is the same costume Charity Wakefield (Marianne Dashwood) wears at Norland Park in "Sense & Sensibility" (2008). The costume is also worn by Amelia Warner (Fanny Price, age 17) in Mansfield Park (1999) and by Jennifer Higham (Louisa Musgrove) at Uppercross in Persuasion (2007) (TV).
The black patterned muslin gown Gemma Jones (Mrs. Dashwood) wears when Edward comes to Barton Cottage is the same costume Billie Piper (Fanny Price) wears to Maria's wedding in Mansfield Park (2007) (TV), and Janet Dale (Miss Briggs) wears at Park Lane in "Vanity Fair" (1998). The same costume is also worn by Pauline Moran (Mrs. Curtain) when Byron arrives for the wedding in Byron (2003) (TV), and by an extra at the Meryton Assembly Ball in Pride & Prejudice (2005).
The white muslin dress with yellow overdress Kate Winslet (Marianne Dashwood) wears during the picnic scene is the same costume a farmhouse servant wears in Eroica (2003) (TV), and Michelle Ryan wears during the scene in which Sir Thomas asks Maria if she wants to marry Mr. Rushworth in Mansfield Park (2007) (TV).
The wine-colored muslin dress, beige pelisse and matching bonnet Kate Winslet (Marianne Dashwood) wears for the Dashwoods' arrival at Barton Cottage is the same costume Cesca Martin wears for her arrival at Regency House in "The Regency House Party" (2004). The dress is also worn by an extra at the Meryton Assembly Ball in Pride & Prejudice (2005).
Amanda Root was originally sought for the role of Marianne, and performed the role at a read-through of an early draft of the script. However, by the time the film was being made, Root could not appear, as she was already working on another Jane Austen film, Persuasion (1995).
The green velvet Spencer vest Kate Winslet (Marianne Dashwood) wears walking in the rain at Cleveland is the same costume Elizabeth Berrington (Charlotte) wears in Quills (2000), and Sally Hawkins (Anne Elliot) wears to the concert at the Bath Assembly Rooms in Persuasion (2007) (TV).
The tall green military-style hat with a peacock feather worn by an extra at the Covent Garden coffee shop is the same one worn by Christina Cole (Caroline Bingley) at Pemberley during the shooting contest in "Lost in Austen" (2008).
The apple-green day dress Harriet Walter (Fanny Dashwood) wears trimming hats with Lucy Steele is the same costume worn by Henry's new partner (seated next to Mary's new partner) at the end of Mansfield Park (1999).
The dark purple velvet and silk gown Harriet Walter (Fanny Dashwood) wears to dinner at Norland Park is the same costume worn by the theatre guest seated next to deSade's wife in Quills (2000), and by Jane How (Lady Holland) at the London party in Byron (2003) (TV).
The pale blue dress with checked trim on the sleeves Emma Thompson (Elinor Dashwood) wears at Barton Cottage is the same costume Anna Madeley (Lucy Steele) wears when Edward calls at Mrs. Jennings' London house in "Sense & Sensibility" (2008), and by a guest at the Meryton Assembly ball in Pride & Prejudice (2005).
The rose lace-covered evening gown Imelda Staunton (Mrs. Palmer) wears playing cards at Barton park is the same costume worn by a guest at the play in Quills (2000).
The green velvet gown with gold and white trimmings worn by Emma Thompson (Elinor Dashwood) to the ball in London is the same costume worn by Christina Cole (Caroline Bingley) in "Lost in Austen" (2008).
The jeweled white gown with dark velvet overdress worn by a guest at the London Ball is the same costume worn by Jacqueline Pearce ( Lady Apthorpe) at the Prince Regent's ball in Princess Caraboo (1994), by Embeth Davidtz (Mary Crawford) for the theatrical in Mansfield Park (1999), and by Jane How (Lady Holland) to a ball in Byron (2003) (TV).
In the DVD extras, Emma Thompson relates how Patrick Doyle was challenged to set Ben Jonson's The Dreame to music. The result is the piece Col. Brandon requests Marianne to play on the pianoforte and the end title music.
