New images of Sienna Miller as Alfred Hitchcock's object of obsession Tippi Hedren have surfaced and it looks like the casting directors couldn't have chosen a more perfect actress to play her.

The stills come from the HBO film The Girl, which unravels the story of Hitchcock's (played by Tobey Jones) infamous stalking and sexual harassment of his muse Tippi Hedren, who actually gave the film her seal of approval and even worked with Miller on the role. 

"He ruined my career but he didn't ruin my life," said Hedren, now 83-years-old."If you are someone's obsession it is oppressive and frightening."

The film premieres stateside on October 20th on HBO.
