The 28-year-old actress - who portrays the legendary action figure in the upcoming Batman movie `The Dark Knight Rises` - convinced an assistant director that living alongside a feline friend would help her to observe the animal`s movements and actions but eventually realised it was an impractical suggestion.
She explained: "I actually had this moment when I convinced one of the assistant directors on the London portion of the film to get a cat with me, the idea being that we were going to get a kitten from a rescue shelter, and he was going to livewith me, and I was going to observe it, and when I left London I was going to give it to her.
"Then, thankfully, her husband pointed out that that was a terrible idea on so many levels, not least of which being that it would probably be really confusing to the cat. So I turned to YouTube instead and got a National Geographic video on cats."
However, living alongside a feline wouldn`t have worked out well for Anne, as she admits her boyfriend Adam Shulman is allergic to cats.
She added: "I am still cat-less. My man is allergic to cats, so that decision is made for me. What we give up for love."
