• Sienna Miller: “She’s a very amazing character to take on. She was very gracious in her kind imparting of information to me.”

• Sienna Miller: “I think it’s always difficult when you’re trying to imitate somebody else as dramatic and brilliant as Tippi. I definitely tried to capture an essence in the film. It wasn’t supposed to be an exact replica. It was difficult during certain scenes, but not nearly as difficult as it was for Tippi. The bird attack scenes took five long days for her. It was about five hours for me. So while I definitely suffered a little bit, it was nowhere near the real thing.”

• Sienna Miller: “I think initially it was a very friendly, director-actress, professional, and quite wonderful relationship that gradually spiraled into something much more sinister as he became more and more obsessed with her, and that’s the story, the demise of that relationship is what the story really focuses on.”

• Sienna Miller: “I don’t think it’s any revelation to hear that Hitchcock had a slightly darker side. You only have to watch his films to see that his relationship towards women is slightly misogynistic.”

• Sienna Miller: “She was very supportive and very involved in the writing, with the writer, so she was very involved every step of the way, but nevertheless it’s a daunting prospect to have somebody playing you and daunting for me to be playing somebody who’s still alive and will then ultimately critique your performance.”

• Sienna Miller: “Obviously, the pressure of playing somebody who exists, it’s always a huge responsibility to try and do them justice, and I was very fortunate that I had Tippi at the end of the phone and on email for any questions that I had. And I just hope we did it justice and did her justice because she’s a very amazing character to take on, and she was very gracious in her kind imparting of information to me.”

• Sienna Miller: “Well, it was far less severe than it was for her, but it was intense nonetheless. We tried to re-create it as much as possible, so I did have live birds being thrown at me, which was not the most pleasant experience, but nowhere near the level of suffering that she had to endure. It was not too pleasant—beaks and flapping—but also really exciting to be re-creating such an iconic scene in cinema.”

• Toby Jones: “I had met her briefly once before, about four or five years before… I’d seen enough of her work to know she was perfectly cast in this role. Despite being the victim of a lot of unwanted attention, she has this sort of natural vivacity and a natural sense of humor to be able to confound all of that and come back. And in a way that’s perfect for Tippi, as well. Sienna was… testifying for the Leveson inquiry into phone hacking on the day we met for rehearsal. So it was an extraordinary amount of pressure. And when you meet her, she’s got this great natural strength, which I certainly wouldn’t have if I had people interested in my rubbish, sifting through my day-to-day affairs.”

• Tippi Hedren: “I do want to say how pleased I am with this film, with Sienna (Miller)’s portrayal, with Julian (Jarrold)’s direction and, of course, Toby (Jones), with his brilliant character depiction of Alfred Hitchcock. They were all brilliant; just wonderful.”

• Tippi Hedren: “She’s wonderful. I just love her. She’s in Pittsburgh right now starting a film and we were emailing each other back and I just thought, ‘Oh what fun it would be to be able to watch it with her [Saturday] night.’”

• Julian Jarrold: “When I was directing Sienna in the BIRDS attack scene, it was incredibly difficult to do, because we had a limited number of birds and we put her up against a wall with a netting and the only way to do it was to keep the camera rolling and just do take after take after take, and I did feel for a bit like Hitchcock during that, because I could see she was suffering a little bit in that scene.”
