Trivia / Breaking Bad S4 E10 "Salud"

• Actor-Inspired Element: Bryan Cranston decided to shoot his scene with Walt Jr. in his underwear, simply because he really enjoys doing so.
• Irony as She Is Cast: Despite Don Eladio being dismissive and unafraid of Gustavo Fring during the events of this episode, Steven Bauer admitted that he was legitimately terrified of Giancarlo Esposito's portrayal of Fring in this episode, and had to work very hard to mask his nervousness when shooting with him.
