A new movie in which former Disney Channel star Hilary Duff will play murdered actress Sharon Tate isn’t even out yet and it’s already getting bad reviews from Tate’s younger sister, Debra Tate.

People reports that Debra Tate had more than a few unkind words about “The Haunting of Sharon Tate,” which we reported on Tuesday. Along with Duff, the film from Skyline Entertainment stars Jonathan Bennett and Lydia Hearst.

Debra Tate’s biggest beef with the project appears to be its premise. The New York Post reported that the movie’s plot is inspired by a quote from Sharon Tate from an interview published a year before her death, in which she reportedly described dreaming about being killed by a satanic cult.

Sharon Tate was 26 years old and eight and a half months pregnant when she was stabbed to death by Charles Manson’s cult followers in 1969.

Debra Tate, who was 16 when her sister was killed, says the dream never happened. People quotes her calling the new movie “classless” and “exploitative.”

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

She called the movie’s premise “a total fabrication,” saying: “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. I checked with all of her living friends. None of her friends had any knowledge of this. Tacky, tacky, tacky.”
