Veronica Mars is an American television series created by Rob Thomas. The series premiered on September 22, 2004, during network UPN's last two years, and ended on May 22, 2007, after a season on UPN's successor network, The CW. Balancing murder mystery, high-school, and college drama, the series features social commentary with sarcasm and off-beat humor in a style often compared to film noir. Set in the fictional town of Neptune, the series stars Kristen Bell as the title character, a student who progresses from high school to college during the series while moonlighting as a private investigator under the wing of her detective father.

The first season had seven regular characters. However, Thomas decided to introduce and eliminate several characters in order to create an "equally fascinating mystery" for the series' second season. Thomas needed "new blood" since he felt unable to bring back the Kanes and the Echolls and "have them all involved in a new mystery". The third season features a cast of ten actors who receive billing, an increase from the nine actors in the second. Three of the regulars in the second season are written out of the series, two new characters are introduced and two others are upgraded from recurring roles.

Main characters

Veronica Mars Kristen Bell portrays the titular Veronica Mars, a high school junior and skilled private detective. More than 500 women auditioned for the role; Bell felt that it was "just luck" that Rob Thomas saw that "I have some sass to me, and that's exactly what he wanted." Bell thought that her "cheerleader looks and outsider's attitude" set her apart from the other women who auditioned.

Duncan Kane

Teddy Dunn portrayed Duncan Kane, Veronica's ex-boyfriend and Lilly's brother. Dunn originally auditioned for Logan but ended up portraying Duncan Kane. Dunn left the series midway through the second season because Thomas felt that the Logan-Veronica-Duncan love triangle had run its course. He needed to put "other guys in her life" to keep the series fresh and attributed Dunn's removal to fan interest in the Logan-Veronica relationship, saying "It became clear that one suitor won out".

Logan Echolls

Jason Dohring played Logan Echolls, the "bad-boy 09er" son of an A-list actor. Dohring originally auditioned for the role of Duncan Kane. After his audition, the producers asked Dohring to audition for Logan's character, who was only going to be a guest role in the pilot. Dohring felt that his audition for Duncan "was a little dark", and was told by the producers that it was "not really right". The producers then asked Dohring to read for the role of Logan. Dohring acted out one scene from the pilot, bashing a car's headlights in with a tire iron. During the final auditions, Dohring read two times with Bell and met with the studio and the network. When reading with Bell, Dohring acted the whole scene as if he was the one who raped her and tried to give the character a certain evil feel.

Wallace Fennel Percy Daggs III portrayed Wallace Fennel, Veronica's best friend and frequent partner in mystery solving. Daggs auditioned for Wallace's role twice before being cast and had to go through three tests with the studio and network executives. During his first audition, Daggs read four scenes from the pilot. Just before his studio test, Daggs read with Bell and had "a great conversation". He said that she "made me feel comfortable about auditioning" and was a big reason why he became more comfortable playing Wallace as the season went on.

Eli "Weevil" Navarro Francis Capra portrayed Eli "Weevil" Navarro, the leader of the PCH Biker gang and Veronica's ally. Despite often being in trouble with the law, Weevil helps Veronica solve many of her cases. He is wrongfully accused of fellow gang member Thumper's murder and is arrested at his graduation. He later becomes a janitor at Hearst College after he is cleared.

Capra reprises his role in the Veronica Mars film, in which Weevil is revealed to have since married a woman named Jade, with whom he has a daughter, Valentina.

Keith Mars Enrico Colantoni played Veronica's father Keith Mars, a private investigator and former Balboa County Sheriff. Keith's targeting of billionaire Jake Kane as the primary suspect for Lilly Kane's death led to a public outcry for Keith Mars to be immediately removed from office. Disgraced, Keith was forced into private investigator work. Veronica often helps him solve cases.

Mallory Dent

Sydney Tamiia Poitier played Mallory Dent, Veronica's journalism teacher at Neptune High, through the first half of the first season. Ms. Dent, as she was commonly referred to, was the only teacher who took Veronica at face value, not based on prejudices. Together with Veronica, she was responsible for uncovering the voting scam that led to Duncan winning the school elections illegally. Ms. Dent left her job after becoming pregnant. Although she was given regular series billing, Poitier appeared in only four episodes but was given credit for seven. Poitier's removal from the series was rumored to be due to budget issues.

Jackie Cook Tessa Thompson portrayed Jackie Cook in the second season as Wallace's romantic interest and the daughter of a famous baseball player. Fan reactions to the character were generally negative, particularly after Veronica witnessed Jackie talking to a guy while dating Wallace. Thomas blamed the character's reception on his error in judgment: he had hoped fans would question whether it was Jackie or Veronica in the wrong; however, the audience automatically assumed that it was Jackie. Thomas decided not to change the story arc he had planned for Jackie, as he believed Thompson was "a fantastic actress and she's got more to play". He said that whether fans ended up liking Jackie was "up in the air", but he hoped that they did because "she's really, really good". Jackie was subsequently written out of the series at the end of the second season.

Dick Casablancas Ryan Hansen portrayed Richard "Dick" Casablancas Jr., an 09er friend of Logan, a womanizer and former high-school bully turned frat boy. Dick was a recurring character in the first season but was upgraded to series regular in the second season.

Beaver Casablancas Kyle Gallner acted as Cassidy "Beaver" Casablancas, Dick's introverted younger brother. Cassidy was a recurring character in the first season, but was upgraded to series regular in the second season.

Cindy "Mac" Mackenzie Tina Majorino portrayed Cindy "Mac" Mackenzie, a computer expert befriended by Veronica. While looking into Mac's parents' past as a favor for her, Veronica uncovers that Mac was accidentally switched at birth with Madison Sinclair by the hospital where they were both born, but the respective parents did not learn about this until years later, by which time they had already grown to love their accidentally adopted daughters. Mac was a recurring character in the first two seasons but was upgraded to series regular in the third.

Parker Lee Julie Gonzalo portrayed Parker Lee, Mac's extroverted roommate at Hearst College, described by Thomas as "everything that Mac is not". Parker was introduced in the third season as a series regular.

Piz Chris Lowell played Stosh "Piz" Piznarski, Wallace's roommate at Hearst College and a music lover with his campus radio show. Piz was introduced in the third season as a series regular and was named after the director of the pilot, Mark Piznarski. The character's role was to have another male friend for Veronica, middle-class and not upper-class. Thomas used the radio show as a narrative device to capture the mood of the university. Throughout the third season, Piz is implied to have a crush on Veronica. The two develop a friendship, although he's initially hurt by seeing her with Logan. After Veronica breaks up with Logan, she starts dating Piz in "Debasement Tapes". When a sex tape of Veronica and Piz starts circulating via email, Logan beats up Piz, believing him to be behind it. Veronica's investigations revealed that the video originated from a Hearst College secret society named The Castle.

Piz reappears in the Veronica Mars film, where he is shown to have since relocated to New York City with Veronica. When she temporarily visits her hometown to help her ex-boyfriend Logan find a lawyer, she gets dragged to her high-school reunion by Wallace and Mac. Piz shows up at the reunion to surprise her, only to join the fight that ensued after Madison Sinclair played a copy of his and Veronica's college sex tape. Piz returned to New York the following morning. After she stayed in Neptune longer than initially planned and didn't show up to meet Piz's parents, he later broke up with Veronica.

Don Lamb Michael Muhney portrayed Don Lamb, the Balboa County Sheriff who won the office from Keith in the recall election spearheaded by Jake Kane. Lamb was a recurring character in the first two seasons, but was upgraded to series regular in the third.

Gia Goodman Krysten Ritter portrays Gia Goodman, a student at Neptune High and the daughter of influential professional baseball team owner Woody Goodman. Gia transfers to Neptune High from a private boarding school. She attends the class field trip to Shark Field and meets Dick Casablancas, his brother Cassidy, Duncan Kane, and Veronica for the first time. Gia rides the school bus on the way to the stadium. However, she opts to ride in Dick's limo with the other "09ers" on the way back. The bus crashes and all of the passengers die, save for Meg Manning. Later in the year, Gia invites Veronica to her slumber party. Veronica attends; however, she has an ulterior motive and is investigating families that Meg babysat for. When Gia is sent footage of herself at her brother's soccer game, she hires Veronica to find the sender. Gia and Veronica's friendship is broken when a feud erupts between their fathers, and she fires Veronica from the case. When Veronica realizes that Gia's stalker is Neptune High's janitor, Tommy "Lucky" Dohanic, she rushes to her aid. Lucky is arrested, but he is released when the Mannings pay for his bail. The next day, he comes to school with a gun looking for Gia; however, he is shot and killed by school security.
