In Lymelife, Rory Culkin plays a teenager dealing with a philandering father (Alec Baldwin), a soul-consuming crush, and a Lyme disease outbreak on 1970s Long Island. His real-life sibling Kieran costars as his older brother, and wouldn't you know it, the duo nail the familial dynamic.
Q: Rory, there's a scene where Kieran's character playfully slaps you around. It looked pretty natural.
R.C.: The director—Derick Martini—would leave the camera running. Kieran slapped me two or three times. Derick refused to cut, and we didn't know what to do. So he just kept slapping me.
K.C.: It wasn't an acting choice. I was just slapping him in the face.
Q: Rory's character loses his virginity in the film. Was it awkward to watch your brother go at it, Kieran?
K.C.: I think it was an amazing scene. Is that weird?
R.C.: I totally agree. Everyone can relate to it. But watching it at the Toronto Film Festival, I shrank in my seat a little bit. Mom was sitting behind me.
Q: What's the best onscreen work you've seen each other do?
R.C.: I would have to say The Dangerous Lives of Altar Boys. That was a badass role.
K.C.: I think some of his best work is in Lymelife, but it's strange to pick one I'm in too. I just like looking at myself. David Walters
