Question: why did once upon a time in hollywood change?
Answer: Margot Robbie as Sharon Tate in Once Upon a Time... in Hollywood. Except that it didn't. ... But Tarantino chose to rewrite history, having the Manson “family” fatefully mistake Dalton's house for Tate's, and never make it out again. Tarantino's Tate tease was just that—a tease.
