The 30-year-old plays the role of Selina Kyle, the Catwoman in the movie, reported Daily Star.
"I would love a spin-off. Actually, it's so embarrassing, I was at a press thing the other night for a screening of 'The Dark Knight Rises', and the moderator asked me, 'So what was it like to say goodbye to the character?' And I burst into tears, because I miss her.
"I'm crying again - I need to stop talking about this, it just makes me cry. I miss her. I love Selina so much and I love her presence in my life and getting to tap into. I'm crying again! Getting to tap into that level of confidence," she added.
