Margot Robbie is a Quentin Tarantino fan from way, way back. The Once Upon a Time in Hollywood star made a self-vow to write a letter to Tarantino asking to work with him, once she felt like she was a good enough actress. Robbie revealed in a Vogue cover story that she did, in fact, write the director a fan letter after seeing the first cut of I, Tonya. “I wrote him and said, ‘I adore your films, and I would love to work with you in some capacity. Or any capacity,’†she said. Tarantino had already been getting prodded by friends to cast Robbie as Sharon Tate, so when the letter came, the timing felt freaky and portentous. Tarantino invited her over to read the Once Upon … script, which took her four hours, during which “Tarantino would occasionally pop in to offer her food or a Victoria Bitter, an Australian beer.†Obviously, she got the part. And how big of a part is it? We’re still working on figuring that out. One other question remains: Did Tarantino just happen to have an Australian beer on hand, or had he got some special for Robbie?
