Candidate passages:
Anne Hathaway portrays Selina Kyle in "The Dark Knight Rises", "Entertainment Weekly" describes Selina as an enigma, a wily and witty con artist, as well as a high society grifter.
Selina is depicted as a femme fatale antiheroine whose actions often blur ethical lines, similar to her portrayal in the comics.
In the film, Selina is hired by corrupt businessman John Daggett to steal Bruce Wayne's fingerprints in exchange for her criminal record to be expunged via a "Clean Slate" computer program, but Daggett tricks her into believing he has it.
These prints are subsequently used by Bane to attack the city stock exchange and bankrupt Bruce with bogus stock trades.
She also steals the pearl necklace belonging to Bruce's deceased mother from his safe.
However, after leading Batman, Wayne's alter ego, to Bane's trap without realizing that they are the same person, she attempts to flee Gotham, fearing that Bane and his men will eventually kill her.
She is arrested by John Blake and taken to Blackgate Prison; she is subsequently released during Bane's coup d'etat.
Although she hoped for the ensuing chaos, she later regrets it.
When Bruce returns to Gotham and offers her the "Clean Slate", she aids Batman and his allies in liberating Gotham City from the League of Shadows, in particular by shooting Bane and helping Batman destroy Talia al Ghul's convoy.
At the end of the movie, Bruce leaves the mantle of Batman behind and enters a relationship with Selina.
She is never referred to as "Catwoman" in the film, although she does receive the moniker in related "The Dark Knight Rises" collectibles and books.
Instead, emphasis is made upon her profession as a "cat" burglar in headlines shown in the film; also, her safecracking goggles resemble cat ears when not in use.

Costume design.
Costume designer Lindy Hemming explained that Bane uses a mask to inhale an analgesic gas, which, in director Christopher Nolan's words, "keeps his pain just below the threshold so he can function."
In designing Bane's costume, Hemming needed it to look "like an amalgam of all sorts of bits and pieces he cobbled together, as he passed through some very remote places.
We made parts of his vest, for example, from fragments of an old military tent.
His clothes are militaristic, but are not in any way a uniform."
Hemming also designed Bane's mask to look "animalistic".
Costume effects supervisor Graham Churchyard created a three-dimensional model of actor Tom Hardy's face and skull to design the mask, allowing the mask to perfectly conform to the contours of Hardy's face.
Hemming personally designed Bane's coat, which she admitted took two years to complete.
Taking inspiration from a Swedish army jacket and a frock coat from the French Revolution, it was designed to make Bane look like equal parts dictatorial and revolutionary.
The design was difficult as Hemming struggled to find a tailor in Los Angeles who could work with shearling.
The Batsuit consisted of 110 separate pieces, each of which had to be replicated dozens of times over the course of the production.
The base layer was made of a polyester mesh that is utilized by the military and high-tech sports manufacturers because of its breathability and moisture-wicking properties.
Molded pieces of flexible urethane were then attached to the mesh, to form the overall body armor plating.
Carbon fiber panels were placed inside the sections on the legs, chest and abdomen.
The cowl was sculpted from a cast of Bale's face and head to become a perfect fit for Christian Bale.
The suit remained unchanged for the film since "The Dark Knight".
In creating Selina Kyle's catsuit, two layers of material were used, with the outer layer being polyurethane coated spandex, embossed with a hexagonal pattern.
The catsuit also consisted of elbow-length gloves, a utility belt, and thigh-high boots with spike heels.
