Esposito has lived in Gus Fring’s skin for more than ten years, giving a priceless performance that it's impossible to imagine anyone better suited for the role.
Gus Fring had a disturbingly sense of calm, making him impossible to read and ultimately scary. Because of his nature, he was able to run an illegal business right under the nose of the DEA, disguised as the force’s biggest supporter.
Giancarlo told Vulture that sitting in silence helped him to play the character.
'I relied heavily on yoga for tranquillity while shooting Breaking Bad,' he said. 'Yoga helped me to remain still and focused on just one thought. I had to shut out all my thoughts and think of nothing to ease and relax. I practised this for years.'
Giancarlo only deepened this yoga and meditation technique when he reprised his role in Better Call Saul.
“We mirror what we see,” the actor further explained. “It’s simple, someone smiles at you, you smile back. Someone tells a joke while laughing, you also laugh. But what if you don’t really get tickled by the joke? Your reaction could be driven by honoring the other person’s emotion.”
Esposito had his character withhold his honest feelings and instead listen to the voice inside him. That helped him protect his emotions and not let his guide down or expose himself.
