Trivia / Breaking Bad S4 E12 "End Times"

• Acting in the Dark: Bryan Cranston did not get the script for the season finale until the preceding episodes had all been shot. He did not know that Walter's argument to Jesse about Gus' responsibility for Brock's poisoning had been based on a lie — and so Walt's performance in this episode was more convincing than usual.
• Enforced Method Acting: Bryan Cranston made sure the writers didn't tell him whether or not Walt had poisoned Brock. Because of this, when Jesse accuses him of doing it while holding Walt at gunpoint, Walt's defense of himself sounds completely honest, highlighting how effective of a liar he can be.
