Zoë Kravitz came up with the 'I have a thing about strays' line in 'The Batman'

• Zoë Kravitz came up with the line about Selina Kyle having a thing for strays in "The Batman."
• Kravitz and director Matt Reeves discussed how the moment came to be during a Q&A for the film.

In one of the latest trailers for "The Batman," the Caped Crusader and Selina Kyle share a humorous exchange.

The rather serious Batman, in Kyle's apartment, gets nuzzled by a few of her felines. Batman, not the biggest conversationalist, states the obvious: "You got a lot of cats."

In response, Kyle says, "I have a thing about strays," a line which could also speak to Batman, who's an orphan himself.

That dialogue was the brainchild of Zoë Kravitz, the actress embodying Catwoman in the forthcoming "The Batman" movie where she stars opposite Robert Pattinson, who's donning the cape.

"When I read the script, it says that she has all these cats," Kravitz told a small group of press, including Insider, during a recent screening and Q&A for the film at Warner Bros in Burbank, California.

"I understood that that was to kind of tip-off the audience she's Catwoman, but I really wanted to understand why," Kravitz added.

Director Matt Reeves said the idea came organically while discussing cats and Kyle's background with Kravitz.

"We talked a lot about the cats," Reeves said, adding that the two also discussed the character's "background" and where "she comes from and what her life was."

"Because she was essentially an orphan, as well, she was a stray," Reeves continued. "She was collecting cats because now she's decided she's gonna protect strays. That whole conversation led to this whole idea. I was like, 'Oh, I love this idea.'"

From there, the dialogue that viewers eventually hear was created.

"I said, that is so great. And she goes, 'So, I could say that right? Something about, you know, I have a thing about strays,'" Reeves recalled.

Reeves was into it, but he was also a bit hesitant in how they could make the line truly work.

Kravitz wasn't.

"And I said, 'Yeah, but how do we set that up?'" Reeves said. "And she goes, 'Oh, that's easy. He can just say, 'You got a lot of cats.' And I was like, 'That is great.'"

"I have to say then, on top of that, to also compliment Rob [Pattinson] again. The delivery of that line, I think, is genius. But anyway, they wrote it and they did it," Reeves said.

"The Batman," also starring Colin Farrell and Jeffrey Wright, is in theaters on March 4.
