"He works his crews pretty hard by always doing more takes than necessary," an insider tells People days after Savage was fired from The Wonder Years reboot for inappropriate conduct. "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."
