In Nasty Baby, Kristen Wiig plays a woman trying to have a baby with her gay best friend and his boyfriend.
But things gets complicated after several confrontations with a mentally ill neighbor named Bishop (House of Cards actor Reg E. Cathey).
Wiig knows a thing or two about questionable neighbors. She was once so fearful of one that she had to find a new place to live.
"It's like so scary that I'm afraid to talk about it," Wiig told me while promoting Nasty Baby with her co-star and director Sebastián Silva. "I mean...it was like a scary—I mean I had to move. Yeah, he was just an unstable person. I wasn't safe being in my apartment. But I moved, and everything was fine."
Silva said Bishop is actually based on a neighbor he had in his native Chile.
Not so scary, Wiig said, was filming a scene in which Siva holds her upside down by her legs after she inseminates herself with a syringe filled with his boyfriend's semen.
"I don't think my dad will see it," she said with a laugh before explaining, "It's kind of a romantic loving scene…I didn't feel uncomfortable at all."
Silva said Nasty Baby shows just how un-sexual getting pregnant can be. "You don't need to have sex. Making babies is like making a cupcake. It could be," he said. "You know, you need two ingredients and an oven to put the two things in…It doesn't need the sensuality or the eroticism. That's dated I feel for baby-making."
Wiig cracked, "You can make cupcakes erotically though."
Nasty Baby is in theaters tomorrow, Oct. 23. The cast also includes Tunde Adebimpe as Silva's boyfriend and Breaking Bad actor Mark Margolis.
