There’s a scene where Lee Ha-nee’s character tries to kill her overbearing husband by stoking up a sauna and the actors spontaneously break out in a rap. The whole scene was improvised since it was originally supposed to take place on a yacht. Although Lee Won-suk was disappointed he would lose his grand scene on a yacht and there was no time to rehearse, that was the day he felt the film definitely delivered some magic. Everyone involved was “on fire.”

“We just went there to shoot and they just went off,” he said with a laugh. “It just went crazy. And that’s the day that we thought this film could work. Because to be honest, as a director, until before that shoot, I wasn’t sure.”

However audiences react, it’s obvious the director and stars had fun making their comedy. For Lee Sun-kyun, one of the most fun scenes was the sauna scene.

“I would definitely say the sauna scene because a lot had changed from what was in the script,” said the actor. “But the way we shot it was just like almost a very cool improvisation and everything just happened. Improvisation, that’s the word, really. It happened really organically. And so it was just such a fun process to be in. And after we wrapped that shoot day was when I really started to have faith that this movie would be completed in a good way.”

For Lee Won-suk, it was a dream project, getting to work with actors he so admired.

“I had the chance to work with the actor and actress that I wanted,” he said. “Because you never get it. Seriously, you never get it. You send them a script, they reject you. You gotta move on. That’s how it is. Because they’re like the top tier actors. So you don’t call and say, hey, do you wanna be in my film? That’s like so Hollywood cliche and that doesn’t exist. We send them the script and we kiss the script. Please let him read my script and please, say yes. With this film that happened. I got to work with them and everyone had fun.”

Killing Romance, which opened the New York Asian Film Festival, will also be shown on July 30.
