Smallville Chloe Chronicles

Allison Mack's character Chloe Sullivan has starred in two promotional tie-in series: Smallville: Chloe Chronicles, and Vengeance Chronicles. There were two volumes of "Chloe Chronicles", totaling eleven mini-episodes. The first volume featured Chloe investigating events which led to the death of Earl Jenkins, who held Chloe and her friends hostage at the LuthorCorp plant in the first season episode "Jitters"; it aired between April 29, 2003 and May 20, 2003, and was exclusive to AOL subscribers. After the first volume received positive responses from viewers, the second volume was created as a continuation, but with Sam Jones III appearing as Pete Ross. This volume used the Smallville comic books as a secondary tie-in to the series. Viewers could watch Smallville, followed by Chloe's Chronicles, and finish with the Smallville comic book which would provide an "enhanced backstory to the online segments". The later series, Vengeance Chronicles, is a spin-off of the fifth season episode "Vengeance". In this series, Chloe joins forces with a costumed vigilante, whom she dubs the "Angel of Vengeance", to expose Lex Luthor's Level 33.1 experiments on meteor-infected people.
The idea for an online show centered on Chloe came from Mark Warshaw, who ran the show's website and was in charge of the DVDs; the series was intended to wrap up "unfinished business" from the television show. Although Smallville: Chloe Chronicles first began airing on AOL, it eventually made its way to the United Kingdom's Channel 4 website. According to Lisa Gregorian, senior vice president, television, Warner Bros. Marketing Services, "Our goal is to create companion programming that offers new and exciting ways to engage the audience, just as music videos did for record promotion." Allison Mack describes the show as "very Nancy Drew and mysterious". She continues, "I think it’s a bit more like The X-Files or NYPD Blue. The Chronicles are like a detective story, with Chloe following clues and interviewing people, going from spot to spot, figuring things out." The scripts were written by Brice Tidwell, but Mack was given script approval for the series, allowing her to review and make changes to the script as she saw fit. Warshaw communicated regularly with Gough and Millar so he could find more unique ways to expand Smallville stories over to Chloe’s Chronicles.
