“It doesn’t matter who it is acting in it it’s just tasteless,” Debra Tate told People. “It’s classless how everyone is rushing to release something for the 50th anniversary of this horrific event.”

Debra Tate was 16 when he sister was murdered in 1969 by one of the followers of Charles Manson’s cult. The 26-year-old actress was married to director Roman Polanski at the time of her murder and was 8 months pregnant with their first child.

Debra Tate commented on the film’s premise, which claims that Sharon Tate had a premonition that she and her former boyfriend Jay Sebring would have their throats slit which is similar to how they were killed by being stabbed repeatedly.

Debra said the so-called dream never happened.

“It’s a total fabrication,” she said.

“I know for a fact she did not have a premonition awake or in a dream that she and Jay would have their throat cut,” she told People. “I checked with all of her living friends. None of her friends had any knowledge of this. “
