Christina Milianhad Jason Dean on her mind when she walked on set of theDexterprequel.
The actress, 43, stars alongsideChristian Slater,Patrick DempseyandSarah Michelle GellarinDexter: Original Sin, and she tells PEOPLE that she had a hard time not thinking about theHeathersposter she had on her wall as a teenager when she was on set.
“My first scene I ever did was with Christian! And I’m — [there’s] this voice in the back [of my head] — myMichael C. Hallwas telling me a whole other story while I’m doing the scene,” she says, referring to theDexterstar’s inner monologue, which narrates the original 2006 series and the prequel, too. “Like, ‘You remember when you… put his poster on the wall? Remember that?'”
Calling Slater, 55, Dempsey, and Gellar, “legends” and “icons,” Milian admits that, aside from herHeathers-related excitement, she had some major nerves working alongside the all-star cast.
“Yeah! Are you kidding me?” she says.

“It took me months to get over the nervous part,” she admits. “And I was still having these friendly, fun, crazy moments with them from day one.”
She decided to just be candid about the nerves, though, and tell her costars how “nervous” but “excited” she was. “That did relieve a little bit of the stress.”
Milian wasn’t the only one fangirling while on set of the prequel series. Gellar, who plays CSI chief at the Miami Metro Police Department Tanya Martin, told PEOPLE, “Heatherswas — and Christian knows this — was my all-time favorite movie in, I think, the world.”

He wasexcited, too, to reunite with Dempsey, 58, who he worked with “30 years ago” on the “funny gangster movie"Mobsters.
“It was wonderful to reconnect with him,” Slater said. “It was really, really great.”
“It is a zinger,” he continued of the 1991 film they worked on together. “It’s really something. We got our Tommy guns and it’s a pretty funny movie. But it was wonderful to reconnect with him. It was really, really great.“Never miss a story — sign up forPEOPLE’s free daily newsletterto stay up-to-date on the best of what PEOPLE has to offer, from celebrity news to compelling human interest stories.
