For instance, the mysterious Man in Black, played by the eternally underrated Ed Harris, has been a continual source of intrigue and plot twists. Turns out Harris himself was only recently finding out about a lot of those twists himself. As filming went on, he was slowly piecing together important details of his character's life. He had no idea that SPOILERS SPOILERS SPOILERS It's Always Sunny In Philadelphia's Jimmi Simpson was playing his younger self until he started suddenly spending copious amounts of time on set. The two never discussed their roles, despite them literally playing the same person. When the twist was revealed, Harris simply patted Simpson on the back and said, "I hear you do a good job." (Presumably, he couldn't watch the show because it's on at the same time as Family Guy.)
Harris was also pretty shocked at the maze twist -- not that he cared to know any of it anyway. At every turn, Harris's main concern is simply doing his job and going home. New guy on set playing his role? Fine. Compelling backstory that sheds light on his mysterious character's origins? In his words, "whatever was going on with him in the past, is the in past." Harris could not be bothered to give any semblance of a fuck about any of that shit.
"When's this freaking movie come out, anyway?"
Meanwhile, American Idol superfan Sir Anthony Hopkins knew even less than Harris, but he cared so much more. Hopkins would inquire about his character's fate and be met with a big, fat silence. He would ask if he could simply know what to expect in the following week's episode and got a resounding "No." The spoiler hoarding got so bad that the good knight's scripts were delivered with the other actors' lines blacked out, so he had no idea what he would be reacting to when he was speaking. Hopkins requested a full script, like any sane person would, but they had the temerity to turn him down.
Those are the heads of the interns who deliver the scripts behind him.
