Shooting in Ireland during the spring and summer is always tricky since the weather can change within minutes. The cricket scene for this film was especially hard to shoot and edit for this reason; the light was different in nearly every shot.
The yellow muslin gown with white ruffle at the neckline that Jessica Ashworth as Lucy Lefroy wears is the same gown worn by Carey Mulligan as Kitty Bennet in Pride & Prejudice (2005). Mulligan wears it in the scene at Longbourn when Mr. Gardiner's letter arrives.
The white muslin frock with red patterned overdress worn by Eleanor Methven as Mrs. Lefroy is the same one Brenda Blethyn as Mrs. Bennet wears in Pride & Prejudice (2005) in the Meryton scene when the Bennets learn that Mr. Bingley has returned to Netherfield Hall.
The pink patterned muslin gown Anna Maxwell Martin (Cassandra Austen) wears during the engagement party scene is the same gown worn by Carey Mulligan (Kitty Bennet) in Pride & Prejudice (2005). Mulligan wears it during the scene in which the younger Bennet sisters visit Netherfield Hall to check on the progress of Jane Bennet, who is ill.
The white overdress with pink and green stripes Jessica Ashworth (Lucy Lefroy) wears to the Laverton Fair is the same costume worn by Carey Mulligan (Isabella Thorpe) when she first meets Catherine Morland in Northanger Abbey (2007).

The trivia items below may give away important plot points.
Jane and her sister both survived a childhood bout with typhoid, which can have a later recurrence similar to Shingles. This is one of the many theories concerning her death at 41. Jane's sister, Cassandra, who also remained unmarried, destroyed most of Jane's correspondence upon her death - leaving many biographers with a lack of information to rely upon. Aside from writing, Jane also lived a very quiet life within her family - sewing, attending church, and occasionally dancing, which she loved. This likely also limits the amount of information left for biographers to study, although her brief friendship with Tom Lefroy and her single-night engagement to Mr. Bigg-Wither appear to truly be the extent of her romantic adventures.
Unfortunately, for a "bio-pic", a great deal of the story is imagined. In fact, most biographers believe that Jane Austen only knew Tom LeFroy for approximately a month, from late 1795 to mid- to late-January of 1796, and that although they did spend a great deal of time together during this period, marriage between them was known to be untenable and that upon realizing the extent of their friendship, Tom was sent away before the end of January, 1796. They are not believed to have ever seen each other again, although Tom did name his eldest daughter Jane, and admitted in his later years to a nephew that he had indeed loved Jane, but that it was in a very "young and boyish way" (being approx 20yra old at the time). Jane stayed so close to her family that she had a very small social life, as did most unmarried women, including her sister, and she therefore most likely replayed this heady month in her mind many times over the course of her life - using it as really her only truly romantic experience on which to draw.
