Eva Marie Saint the star of North by Northwest was recently interviewed by Turner Classic Movies about her work:

“Hitchcock was a gentleman, he was funny, he was so attentive to me, with the character, and he cared about everything my character Eve Kendall wore. He had an eye for the specifics of the character.” You can read the whole story here:

“Everybody had a different experience with him. There were six of us Hitchcock blondes, and it’s like we all were married to the man at one time or another and we all have a different take on him. Each actress was at a different stage of their life, we were different ages, some married, some not. My experience with Hitch was one of utter respect, warmth, friendliness and humour, and North by Northwest was a glorious time in my life. For me, it was beautiful and memorable and Hitchcock was funny, respectful and dear.”
