Once Upon a Time...in Hollywood: The Real People Featured in the Tarantino Film

Quentin Tarantino loves an homage, and Once Upon a Time…in Hollywood is basically just that: a sprawling, meticulous ode to the city and the film industry in 1969. While stars Leonardo DiCaprio and Brad Pitt play fictionalized characters (inspired by a true bromance), the movie is filled with straight-on versions of real people, from Sharon Tate and Jay Sebring to darker figures like Charles Manson and his many followers. Here’s a brief guide to the who’s who of the film, including pop-up appearances from surprising figures like Bruce Lee and Mama Cass.
