The characters, played by Danny DeVito and Michelle Pfeiffer, respectively, famously teamed up in 1992’s Batman Returns, and while that movie remains Penguin’s last live action theatrical appearance thus far, Catwoman was played in 2012’s The Dark Knight Rises by Anne Hathaway.
Penguin and Catwoman were also recently main characters on the TV series Gotham, played by Robin Lord Taylor and Camren Bicondova, respectively.
Penguin and Catwoman have been part of The Batman mythos since almost the very beginning, although nowadays the latter is frequently depicted as an anti-hero who is still the Dark Knight’s most recurring love interest.
