The film dramatizes the young Hedren's relationship with the obsessive Hitchcock, who reportedly made sexual advances against her and blacklisted her from future films.
The real Tippi Hedren, who said that Hitchcock "ruined" her career, has already voiced her approval for Jones' portrayal of the famous director.
"I have to say that when I first heard Toby's [Jones] voice as Alfred Hitchcock, my body just froze," she said in August.
'The Girl' airs October 20th at 9PM on HBO.
