Charlie Hall says the most valuable acting advice he ever received from his mom, Julia Louis-Dreyfus, was surprisingly “basic.”

“When I first started acting, I was like, ‘Mom, how do I become good at this?’ and she was like, ‘I think you should read every script and ask yourself, how [would] a human say the words you’re about to say?’” he told Page Six exclusively at the premiere of “Monster: The Ed Gein Story” on Tuesday.

Hall shared that he knows the advice may sound trite, but explained it was actually a powerful lesson.

“Sometimes in the flurry of acting techniques, you kind of forget that your first, and kind of only job, is to feel like a real human.”

“The Sex Lives of College Girls” star is the youngest son of the “Seinfeld” alum and her husband, Brad Hall.

Hall, 28, is following in his mom’s footsteps, albeit in slightly darker territory, with a role in the upcoming Ryan Murphy “Monster” series. He plays Deputy Frank Worden, who helped investigate the crimes of Ed Gein.

Gein, also known as the Butcher of Plainfield, was a killer who exhumed corpses and created grotesque keepsakes from their bones and skin. He also assiduously peeled off people’s faces, including his mother’s, and wore them as masks.

His macabre crimes have inspired a myriad of fictional serial killers, most notably Norman Bates in “Psycho,” Leatherface in “The Texas Chainsaw Massacre” and Buffalo Bill in “The Silence of the Lambs.”

Gein died in 1984 while confined to a psychiatric institution.

Hall said he didn’t experience nightmares while filming, but “I had to make a point to watch something funny when I got home.”

Other celebrities on the red carpet included Charlie Hunnam, who plays Gein, Laurie Metcalf and Tom Hollander.

“Monster: The Ed Gein Story” will be available for streaming on Netflix on Oct. 3.
