The actress said that while she usually takes Valentina to the set of any film she's working on, she left the 4-year-old at home while shooting the violent movie.
"She's not going to watch this movie," Hayek said while visiting the Tonight Show. "Actually, this was the only movie that she was not on the set.
"I usually bring her on the set and she always likes to sit right next to the monitor and she bosses everyone around," she added.
The 45-year-old went on to say that the film's director would never have allowed the young girl to be on set anyway.
"I know Oliver Stone would have not let [Valentina] come in and say, 'Excuse me, Oliver, let me just take over the set'. No," Hayek said.
Stone has insisted that the extreme drug war depicted in Savages could one day become a reality.
