Lizzy Caplan faced significant challenges to secure her now-iconic part as Janis Ian in the 2004 comedy “Mean Girls”. During a recent interview, Caplan explained that her journey through the difficult audition process highlights her determination in overcoming resistance from casting decision-makers as she vied for the coveted role. The story behind the Lizzy Caplan Mean Girls casting reveals the persistence required to land such a memorable character and provides surprising insight into the movie’s early development.
A Long and Competitive Audition Process
Caplan disclosed that the road to joining the “Mean Girls” cast was far from straightforward. While discussing her experiences on the podcast “Podcrushed” with Penn Badgley, she explained how the audition process was unusually lengthy and competitive, as many aspiring cast members were evaluated for the two main roles, those of Cady and Regina George, famously played by Lindsay Lohan and Rachel McAdams.
“It was just the funniest script I had ever read,”
Caplan remarked.
“I wanted to be in it so bad. I fought so hard and then it worked out.”

Caplan shared that after initial auditions, the casting directors organized actors into groups for callbacks, and everyone was tested for one of the lead female parts. Only later in the process did the team begin sorting among other roles, such as Janis Ian, as the choices narrowed.
Studio Preferences and Last-Minute Changes
Despite Caplan’s enthusiasm, not everyone involved in the casting was immediately convinced she was the right fit for Janis. There was notable interest from the studio to cast Kelly Osbourne in the role, as she was suggested as a potential pick for Janis Ian.

“I went in and they were resistant to casting me,”
said Caplan, highlighting the initial skepticism she faced.
“Somebody reminded me of this recently: the studio wanted Kelly Osbourne to play that role.”

The turning point in her audition came with some creative problem-solving. A Canadian hairstylist helped Caplan transform her appearance, giving her the look required to convince studio executives she could embody Janis’s goth persona.
“We went to Hollywood Boulevard and put on dark wigs and just anything to send them screen grabs of me looking like a goth kid,”
Caplan recounted. — Lizzy Caplan, Actress
Landing the Role and Celebrating Success
Caplan vividly remembers the moment she received news of landing the part. The sense of excitement and satisfaction was memorable, as it was a goal she had fought hard to achieve.
“I don’t remember how long the process was, but I remember getting the phone call and where I was when I got the phone call that I got the part,”
Caplan shared.
“How many times has that really happened to you in your career: that you just want to celebrate and it’s nothing but exciting?”

After months of campaigning for the role, Caplan’s perseverance paid off, and she officially joined a cast that included Lindsay Lohan, Rachel McAdams, Jonathan Bennett, Daniel Franzese, and others. This accomplishment marked a pivotal moment in Caplan’s career, opening doors to future roles and critical recognition.
The Unique Experience of Filming Mean Girls
Caplan spoke about what it was like to be on set in Toronto, where filming took place for nearly three months. The entire cast, including Daniel Franzese (Damian Leigh) and Jonathan Bennett (Aaron Samuels), lived together in a hotel, creating a collegiate environment that left a lasting impression on her.
Caplan explained,
“We lived in the hotel and it felt like a dorm, which, looking back, was a really important thing for me.”
She reflected on the camaraderie that developed during production and how those experiences compensated for the traditional college life she missed pursuing her acting career.
“All of my friends, I would go visit them in college and they were having these really exciting new experiences,”
Caplan said.
“I was in Los Angeles, going to the supermarket at three in the morning, hoping that anything would happen to me, like I would meet anybody and anything would happen.”

Caplan said.
“Just being in a movie felt like such a big deal to me at the time.”
