This is not okay, guys.
>During a scene in the reshoots, Joss Whedon gave one of the actors a bit of direction and told him to say his line as written. As the actor was walking toward his mark, he said absently, "It’ll be something like that, yeah." It was at this point that Whedon stopped him in his tracks, called the entire cast over to him, and sternly reprimanded them about this practice they had apparently developed wherein they just say whatever they want, rather than what was written. He made it clear to them that this practice was to come to an immediate end, and it did. Afterward, it was pointed out to Whedon that, essentially, Snyder’s attitude towards the script was more indifferent and "free-flowing", whereas he was stricter and to the letter.
