Although each episode leads us to outlandish scenarios, Charlie and Pim often speak with surprising normality during their adventures. The comedy in Smiling Friends shines brightly through its dialogue construction. Sometimes it's just about small mutterings, stammers, strange gestures, and misunderstandings in casual conversations that seem unrecognizable compared to real-life interactions. This is where the voice acting truly shines, with most performances done by Hadel and Cusack themselves, who bring an enormous variety of personalities, tones, attitudes, and memorable lines. And when they're not involved, other animators and well-known YouTube personalities lend their voices or even appear directly in an episode.
