First impressions aren't always easy, but when they involve superhero costumes and fight scenes, they're definitely memorable. In a new interview with Entertainment Weekly, Robert Pattinson explained that some of the first scenes he filmed opposite Zoë Kravitz involved fistfights, not-so-well-ventilated costumes, and — embarrassingly enough — plenty of sweat.

In one scene, Batman encounters a pre-Catwoman Selina Kyle as the two explore Gotham City on the hunt for Riddler. Naturally, as is the usual M.O. for superhero movies, the two end up in a fistfight, which Pattinson says was a very memorable way to meet his co-star and introduce their dynamic to the audience. But, it's not the chemistry he remembers most, he also noted that his batsuit didn't offer up many opportunities for his sweat to go anywhere other than right onto Kravitz.

"There's only one place where sweat can be released," Pattinson said. "And it would drop directly between Zoë's eyes or nose. I could almost see it quivering at the end of my nose like, 'Don't drop!' It's like Mission: Impossible."

"I'd just be trying to do the scene, but also just looking at the one bead of sweat that I knew was about to fall," Kravitz added.

She added that it was a nice way to start their working relationship, since the two could get to know each other without having to spout lines and lines of dialogue without sparking any kind of connection.

"It was a really intense way to kick things off," Kravitz said. "It was almost good because I had all this training beforehand, and learning that fight was very intense. But there's just something comforting actually in starting [with] something that's more physically-focused versus a monologue or something. That's the stuff that actually is more intimidating to do, especially in a film like this."

And they had plenty of time, Pattinson said. If office icebreakers are awkward, imagine doing it in full costume.

"That was a pretty rough introduction to playing a character because Matt likes to do a lot of takes, and we were shooting a fight," he said. "It's hard to fight in those suits. We were doing that for weeks."
