Cassie Lang May Just Be The Key Component To Ant-Man And The Wasp: Quantumania

Since 2015, Scott Lang (Paul Rudd) — better known as Ant-Man — has featured in the Marvel Cinematic Universe, and with each passing appearance, his corner of the franchise has become more important. He first thwarted the evil plan of Darren Cross (Corey Stoll) and then helped Captain America (Chris Evans) fight against the Sokovia Accords. From there, he visited the dangerous and unpredictable Quantum Realm, which turned out to be the key to time travel and, therefore, the defeat of Thanos (Josh Brolin), who used the Infinity Stones to wipe out half of all life in the universe.

As if using his, or, rather, Hank Pym's (Michael Douglas), size-altering science to save half of the universe wasn't enough, somehow Lang is headed for another life-changing adventure. In "Ant-Man and the Wasp: Quantumania," he'll once again venture to the Quantum Realm and confront mysterious forces, but thankfully, he's not going alone. In addition to Pym and Hope (Evangeline Lilly) and Janet van Dyne (Michelle Pfieffer), he's going microscopic alongside his daughter, Cassie Lang (Kathryn Newton), who's gone from an innocent child to a capable adult throughout the "Ant-Man" trilogy.

In fact, Cassie is such an important character in "Ant-Man and the Wasp: Quantumania" that one could argue that she's the key component to the entire film. Here's why.

Cassie's scientific mind is the catalyst for Quantumania's story

Ahead of the release of "Ant-Man and the Wasp: Quatumania," director Peyton Reed discussed the film with Entertainment Weekly. During the chat, he spoke on the character of Cassie Lang and how she has evolved across the three "Ant-Man" movies. In addition to delving deeper into her bond with her father, Reed has gotten to explore her more scientific side in the upcoming film. He explains, "She has become a scientific mind in her own right. She's been going through Hank Pym's old journals and notebooks and has really latched on to this idea of quantum science and quantum technology."

We get a taste of this in the first "Quantumania" trailer, where we see Cassie develop a new piece of technology to communicate with the Quantum Realm — a good idea that quickly backfires in the worst way. This will bring the Ant-Family face-to-face with the imposing Kang the Conqueror (Jonathan Majors), who is an incredibly powerful and destructive presence in the MCU. This won't make things any easier for Cassie, who, much like Kathryn Newton herself, is just trying to do her best. "She's just trying to figure out how to be a good person and, you know, making a lot of mistakes. She's kind of a mess really, yeah, and so am I," Newton told Entertainment Tonight.

"Ant-Man and the Wasp: Quantumania" premieres on February 17, 2023, and when it does, expect Cassie Lang to finally take the spotlight.
