Nosferatu director Robert Eggers recently found out the hard way that, while practical effects are sometimes the best way to go, they also smell really, really bad.
"There's 5,000 real rats. So basically, if there's rats in the foreground, they're real, and they thin out and become CG rats in the background," Eggers explained during a Q&A that followed an exclusive screening of the film in Los Angeles, hosted by Guillermo del Toro. "And they were well-trained – like when the rats like run off of the ship, they were on buzzers. And the rats that were on Emma Corrin... I didn't know that rats are incontinent. And so the smell is insane."
