From potential role swaps to who wore a wig, ET is celebrating the 15th anniversary of Mean Girls this year by digging up behind-the-scenes secrets and reflecting on the popular film with its leading ladies.
April 30 marked 15 years since the teen comedy starring Lindsay Lohan, Rachel McAdams, Tina Fey, Amanda Seyfried and Jonathan Bennett slid into cinemas and became a cult hit.
“Mean Girls still to me feels like it was yesterday,” Lohan told ET’s Nischelle Turner.
“Oh my gosh -- shooting that movie, I had never been in a movie before,” Tina Fey added while chatting with ET’s Lauren Zima. ”I had no idea. I had just done Weekend Update. But it was a good time.”
While Lohan will forever be known to many for her role as Cady Heron in the 2004 film, she wasn’t necessarily who filmmakers were eyeing up for the character. In fact, Lohan and McAdams (who played meanie Regina George) could have ended up with each other’s roles. But following Lohan’s portrayal of Anna in Freaky Friday, filmmakers were wary that fans might not accept her as a villain.
“I knew she would be able to play Cady and go from being completely innocent -- someone who knows nothing -- all the way to being a horrible beotch and back to being a good person again,” said Fey, who also wrote the film.
Seyfried, who was 17 at the time, also tested for the role of Regina, but was found to be better suited to the part of ditzy Karen.
“It was the first movie I'd ever done,” Seyfried told ET in March. “I had the best time.”
Meanwhile, James Franco was considered to portray Aaron Samuels, a role which went to Bennett.
“It wouldn’t have been the same without him,” Seyfried said of Bennett at the time.

'Mean Girls' Turns 15! Behind-the-Scenes Secrets With the Cast
In other fun facts from the set, McAdams couldn’t fully bleach her hair, so she wore a wig in order to go blonde for the role.
“I just thought that was very Regina -- long, blonde, Barbie hair,” McAdams said during an interview on set at the time of filming. “The color looks perfect.”
ET also spoke to Lacey Chabert (aka Gretchen Wieners) who shared how her 2-year-old daughter, Julia, recently saw the scene where the girls are performing “Jingle Bell Rock,” and exclaimed, “That’s Mama!”
“Fifteen years -- how is that possible?" Chabert said. “It feels like yesterday. I will never forget making that movie and I am so flattered people still love it and talk about it as much as they do. I’m honored to have been a part of it.”
"I mean, it's unbelievable how iconic this movie has become and how many people still find it and discover it each year," Daniel Franzese agreed while chatting with ET Live's Denny Directo and Tanner Thomason. "I just think it's an honor to be a part of something so relevant."
One of the ways the flick finds relevancy is thanks to its impact on the LGBTQ community, largely through Franzese's character, Damian, which is something that the actor is immensely proud of.
"I think Damian is one of the first LGBTQ characters, especially one of size, that resonated with a lot of people," Franzese explained. "... It was a movie where Damian was just able to be himself and be comfortable in his skin and not have to fear for his life and just breathe and be able to survive. I think that resonated with a lot of people."
As for the possibility of a reboot, Chabert agreed it would be fun to revisit the film. “I haven't heard anything about it officially, but it was such a fun character that I think it would be so much fun to revisit these women and see where they are now.”
