It's wild how fragile and unknown memories are for us. Great quote from Bryan Cranston:
Cranston said he told Muniz not to worry about what he can’t remember. Cranston starred with Muniz in 151 episodes of Malcolm. “They are still [his] experiences,” Cranston said. “It will me my job, I will tell him, ‘remember this? Remember that on Malcolm?’ What a life for you.”
