Veronica Mars

The character Veronica Mars is a student who progresses from high school to college while moonlighting as a private investigator under the tutelage of her detective father. In each episode, Veronica solves a different stand-alone case while working to solve a more complex mystery. The first two seasons of the series each had a season-long mystery arc, introduced in the first episode of the season and solved in the season finale. The third season took a different format, focusing on smaller mystery arcs that would last several episodes.

Thomas initially wrote Veronica Mars as a young adult novel, which featured a male protagonist; he changed this because he thought a noir piece told from a female point of view would be more interesting and original. Filming began in March 2004, and the series premiered in September to 2.49 million American viewers. The critically acclaimed first season's run of 22 episodes garnered an average of 2.5 million viewers per episode in the United States. The series appeared on several fall television best lists and garnered awards and nominations. During the series' run, it was nominated for two Satellite Awards, four Saturn Awards, five Teen Choice Awards and was featured on AFI's TV Programs of the Year for 2005.

The show was cancelled after its third season, and Thomas wrote a feature film script continuing the series. Warner Bros. opted not to fund the project at the time. On March 13, 2013, Bell and Thomas launched a fundraising campaign to produce the film through Kickstarter and attained the $2 million goal in less than 11 hours. They accumulated over $5.7 million on Kickstarter. The film was released on March 14, 2014. An eight-episode fourth season was released on July 19, 2019, on Hulu. In November 2019, it was announced that there were no plans for Hulu to order a fifth season.
