• According to Alessandro Nivola, who played the character Aleksei Sytsevich, the bizarre bird-like screech his character lets out was a last-minute improv that the director loved and insisted they keep in the film
• Nivola revealed that the screech was inspired by the sounds his young kids make when they're playing, adding that it perfectly captured the character's over-the-top emotional meltdown in the scene
