Filming

Hitchcock was forced uncharacteristically to do retakes for some scenes. The final shot in the shower scene, which starts with an extreme close-up on Marion's eye and zooms in and out, proved difficult for Leigh because the water splashing in her eyes made her want to blink, and the cameraman had trouble as well because he had to manually focus while moving the camera. Retakes were required for the opening scene because Hitchcock felt that Leigh and Gavin were not passionate enough. Leigh had trouble saying, "Not inordinately" for the real estate office scene, requiring additional retakes. Lastly, the scene in which "Mother" is discovered required complicated coordination of the chair turning around, Vera Miles (as Lila) hitting the light bulb and a lens flare, which proved to be difficult. Hitchcock forced retakes until all three elements were effected to his satisfaction.
