Apparently, Fred Savage was quite angry on sets. Via PEOPLE:
According to the insider, Savage is “quick to anger.” Part of his process includes overshooting, a common practice in the industry but one that the source explains only makes things harder on the crew.
“He works his crews pretty hard by always doing more takes than necessary,” the insider says. “Some directors just overshoot. Sometimes they feel like they didn’t get the performance or want to try another angle or things like that. He overshoots and the days are longer, therefore giving more opportunities to snap at people.”
A second source adds that Savage “can have a temper and occasional outbursts.”
