ET spoke with Kravitz at the film's premiere in New York City, where she shared how excited she is to celebrate Selina Kyle.
Kravitz, who dazzled in an all-black number with a special nod to "the cat," spoke to ET's Rachel Smith about her look, and the Catwomen of the past who inspired her portrayal of Selina Kyle.
"I mean, I have literal cats on my dress, what do you think?" Kravitz said of channeling Kyle with her red carpet look. "I think she's just someone who I've been inspired by for so long. I'm so excited to celebrate her on this journey of releasing the film."
The black, floor-length strapless gown featured a corset-like lace-up detail at the bodice, with two sets of cat ears at the bust to pay homage to Kravitz's role of Catwoman. Kravitz stars as the feline criminal opposite Batman, played by Robert Pattinson, in the action-packed Matt Reeves-directed comic book movie.
For her portrayal of Kyle, Kravitz told ET she looked to other famous faces who've taken on the role, including Eartha Kitt, Halle Berry and Michelle Pfeiffer.
"I was inspired by all of them, really, the way that each and every one, from Julie Newmar to Earth Kitt, Halle and Michelle, they completely owned the character and made the character their own," she shared. "And I was inspired by the fact that they all did their thing."
Kravitz, who lives in the Big Apple, had plenty of support behind her at the film's New York premiere, from Jason Momoa -- who hit the carpet with Kravitz's younger siblings -- to her boyfriend, Channing Tatum, who flew out to the city with Momoa to be there for her.
"Oh, you know, we're in New York tonight, and I live here. I have a lot of friends and family here tonight," Kravitz gushed. "So, I feel very lucky to have a lot of people who love me here tonight."
Momoa, who attended the premiere with his and Lisa Bonet's two kids -- 14-year-old daughter Lola and 13-year-old son Nakoa-Wolf -- told ET that Bonet couldn't be at the premiere, and he was there to show his support.
"We're just so proud," he said. "Lisa couldn't be here so we're representing, me and the babies. We're very excited to just be here...It's still family, you know?"
The movie has been a long time coming for the Big Little Lies actress. Back in 2019, Momoa told ET that Kravitz landing the role was "perfect casting."
As he proclaimed, "She's gonna kill it."
