Debra Tate, sister of the late Sharon Tate, is shouting out Margot Robbie after the release of the new Once Upon a Time in Hollywood trailer.

Per TMZ, who's spoken with Debra about Quentin Tarantino's Cannes-premiered ninth feature before, there was one scene in particular (the one in which Margot's Sharon heads to a theater to see her own movie) that had her temporarily worried. After the trailer dropped Tuesday, however, those worries were eased.

"Depending on how Margot played it, it could've appeared egotistical," Debra said in an article published early Wednesday. "But, no, she did a beautiful job. Sharon did not have an egotistical bone in her body . . . Margot captures Sharon's sweetness very nicely."

Previously, Debra revealed she had been given access to the film's script and even invited down to the set. Back in July, she said Tarantino had approached her to discuss any concerns she may have over the Charles Manson-adjacent story he's telling. After the meeting, Debra gave her approval. 

"This movie is not what people would expect it to be when you combine the Tarantino and Manson names," she said at the time. The film—also starring Leonardo DiCaprio and Brad Pitt, among many others—is due for a stateside release July 26. It's already being described as "brilliant" and "intensely unsettling" following its Cannes premiere.

Sharon Tate and four others were found dead in Los Angeles on Aug. 9, 1969 after being murdered by members of the Manson Family cult. At the time, Sharon was pregnant with her and Roman Polanski's child.
