1. The new DCEU envisions an old Batman
After the plot details of the upcoming [Batman v Superman: Dawn of Justice] and films revealed up to date, we know that Batman / #BruceWayne is an "old, more broken, kind of f**ked up hero" and has been fighting criminals for several years now. So we can assume that many of his friends and foes has also been there for several years like the Joker, Robin and maybe... #Catwoman?!
2. There is a chance to depict more mature characters
This is the perfect chance to see some of the classic characters from the Batman mythos in a more complex and mature way, as never portrayed in any film before. It is the time to know Dick Grayson being Nightwing, Barbara Gordon taking care of business as Oracle and seeing Selina Kyle as an experienced Catwoman, in her 50's'?
3. #SelinaKyle is an old-time love
After all, Selina Kyle is the one 'true love' of the Bat and the most enduring relationship he has ever had in spite of their complications. As we've seen in the comics, he has chosen her several times over Talia al Ghul, Demian's mother which is Bruce's first born son. (Yep, this is complicated! Even in the comics this kind of things can happen).
We've seen older versions of Selina Kyle in graphic novels like Frank Miller's most famous interpretation of Batman: The Dark Knight Returns (Which, by the way, is part of Zack Snyder's inspiration for this new Batman DCCU ). In the graphic novel an older Selina owns an escort company and seems to care a lot about 'the every day more decadent' Bruce Wayne.
4. She is the most iconic modern-era #Catwoman
We've seen some film interpretations of the character in the last 20 years and even though Nolan's version of it takes a quite different angle, Anne Hathaway fell flat and it wasn't as iconic as Pfeiffer's once was. Ultimately the Batman Tim Burton-Era was the most iconic and influential work for later modern adaptations of the characters setting a darker tone in the entire Batman mythology. Catwoman became almost a religion in the 90's.
From comics to animated series to video games to tv series, there is a reminiscence of Burton's Catwoman. Even Camren Bicondova, who plays a very young Selina Kyle in WB's Gotham tv series, is like a younger version of Michelle Pfeiffer.
5. She has portrayed the most deadly femme fatale in any #Batman film
The Batman filmography has had a wide range of female characters, some of them taken directly from the classic Rogues gallery. Yet, not even Talia al Ghul in Nolan's Dark Knight universe was as deadly and subtle as Batman Returns' Catwoman.
6. Fans want classic characters in the new films
Despite the multiple Catwoman versions on film after the Tim Burton-Era (Let's not talk about Halle Berry's version) we are ready to see a more comic book type of character in the big screen. Michelle Pfeiffer can bring to the fans the feeling of seeing a classic character back from death in a new universe, her interpretation has become a classic for every Batman fan.
7. She is excellent actress
During her career, she has won numerous awards including the Golden Globe Award for Best Actress - Motion Picture Drama, the BAFTA Award for Best Actress in a Supporting Role and received three Academy Award nominations.
8. She is the one and only #Catwoman
Michelle Pfeiffer really embodied a cat, which is the reason her interpretation turned to be the most meaningful up to date.
9. She still looking the part
It wouldn't be difficult to introduce her in the new DCCU. In her 50's Michelle Pfeiffer still looking great and she easily could kick some asses! She has expressed her excitement on reprising the role before and it is time for that to happen.
