Laurel Jane "Laurie" Jupiter (born Juspeczyk), is a former masked vigilante formerly known as Silk Spectre, taking up the mantle from the original Silk Spectre, her mother.
Malin Akerman plays Laurie in the film. In it, her mother's last name is never mentioned to be "Juspeczyk". (However, Laurie's last name is revealed to be "Juspeczyk" when her biographical information appears after she looks at her hand while wearing Dan's night-vision goggles.) Also, Laurie's suit is somewhat different from the graphic novel. It's tighter, made of latex and includes a pair of thigh-high boots instead of high-heels. Additionally, it lacks the skull choker around her neck.
The manner with which Laurie discovers the identity of her biological father also differs in the film: in the original story, while on Mars with Dr. Manhattan, he unlocks her repressed thoughts that she'd long blocked. In the film, Manhattan touches her head and unlocks that part of her subconscious.
Finally, neither Laurie nor Dan adopts new identities at the end of the film, because they are immune to arrest so long as the authorities believe Dr. Manhattan is still watching over them. Sally visits them at Dan's apartment.
Just like many characters in Watchmen, Laurie is portrayed as having superhuman physical abilities, as she could break bone effortlessly with one strike and send people flying through the air or cause them to flip into the air. She was unfazed by the strength of her opponents and could overpower them with little to no effort. Nite Owl II and the Comedian seemed to match her in strength and fighting abilities, but all of them were surpassed by Adrian Veldt. She also could jump from several feet and perform a combat roll without any harm or weakness.
Laurie has long brown hair with bangs, brown eyes, fair skin, full lips, and a beauty mark below her right eye. She is 5,8. Laurie is said to look a lot like her mother, although she has brown hair while her mother has auburn hair. Laurie is also noted to be just as beautiful as her mother, if not more. People say that she has a very beautiful smile. She has long graceful legs and quite an athletic figure, due years of martial arts and gymnastics training. Laurie's Silk Spectre costume in the graphic novel is a black bra and thong, covered by a see-through yellow dress. She also has black high heels and a choker necklace with her costume. Her movie outfit lacks the choker and is more revealing, although it sports the same basic colors.
- Master Martial Artist: Juspeczyk is an master martial artist. She has trained ever since she was five years old by her mother and several other teachers. She is able to hold her own against several muggers and other foes without being injured.
- Master Acrobat: Juspeczyk is also a incredible gymnast after training all her life. From practicing gymnastics, Laurie has excellent balance. She is able to perform flips and kicks while wearing high heels.
- Master Marksman: Juspeczyk is able to use firearms, as she shot a bullet at Adrian, which would have hit his chest had he not moved his hand in the bullet's path and had it lodged into his palm.
Just like many characters in Watchmen, especially in the film, Laurie is portrayed as having superhuman physical abilities, as she could break bone effortlessly with one strike and send people flying through the air. Laurie easily maneuvered in between multiple knife strikes and defeated several muggers at once. She was unfazed by the strength of opponents much larger than her and could overpower them with little effort. She could jump from a distance of over a dozen feet and perform a combat roll without any harm or weakness. Nite Owl II matched her in strength and fighting abilities, and both of them were surpassed by Adrian Veidt. These extreme physical abilities likely come from unlocking hidden human potential through a lifetime of strict training, as implied by Adrian Veidt who was researching this along with other theoretical sciences.
Laurie Juspeczyk is liberal-thinking and said to be a "modern" woman. Laurie may be proud of her Polish heritage, which could account partly for her insistence to be called by her real last name, but she was not inclined towards crimefighting initially and she seems to have bitterness for the 'Miss Jupiter' christening. She is vocal in her feminist and humanitarian concerns and is quite a conditioned fighter, and at the start of the story is shown to have a strained relationship with her mother, another reason for her to not like the Jupiter name. Driven by the memories of her own experience, Sally tried to keep Laurie from knowing some of the harsher realities of the crime-fighting life; for example, she didn't allow her to read Hollis Mason's autobiography Under the Hood, which included The Comedian's sexual assault on Sally, something Laurie knew nothing of at the time.
