A long time ago, we used to be friends.

While Veronica Mars, the TV series ended in 2007, many of the guest stars are major stars today. The stars range from a reality star to one of the Mean Girls.

The series stars Kristen Bell as Veronica Mars, a teenager who does private investigation work. In the third season, she gets a real PI license. Throughout the series she gets help from her friends Wallace (Percy Daggs III), Weevil (Francis Capra) and Mac (Tina Majorino). The four often work together to clear their names or their friends’ names in cases.

Veronica has multiple love interests throughout the series. There is her first boyfriend Duncan Kane (Teddy Dunn), who breaks up with her because he believes they are half-siblings. There is Troy (Aaron Ashmore), who Veronica dumps after she realizes that he is a lying drug dealer. Then there is Piz (Chris Lowell). She dates Piz in college and even in the movie. However, Veronica is always drawn to Logan (Jason Dohring).

Logan and Veronica end up together after the movie. Just as Logan said in the second season of the show, they have an epic love story. After Logan’s second girlfriend is murdered, Veronica helps to clear his name and then they fall back in love.

Veronica Mars only had two seasons before it was cancelled. However, after a kickstarter campaign, the Veronica Mars movie was released, updating us on all of the characters’ unfinished stories.

In 2004, most of the people on the list weren’t big names. However, ten years later, it is shocking to even think that some of these people had such small roles. There are more than ten big names in the series. Others include Paul Rudd, Kevin Smith and even a young Alyson Hannigan.

Here are ten people who were guest stars on Veronica Mars.
