During the same interview, she recalled the intense auditioning process for the role, where they asked her how much she  weighed, [her] height and [her] bust size. 

 And I thought,  This is silly. This is not for me. I want to stay in the theater. Which I think I certainly would have had we stayed in New York,  she explained before reminiscing about meeting Brando and improvising a scene together.

 He put the radio on, and we started dancing,  she said.  He did something to flip my skirt, and I was so embarrassed I cried a little bit afterward. It was too much; it was all too much. But Kazan saw the chemistry, and he could see that it could work for the movie. 

Saint went on to gush about Brando, calling him  wonderful  and  probably the finest actor I've ever worked with.

Hitchcock ultimately cast Saint over a slew of other blondes in  North by Northwest,  which is widely considered one of his masterpieces and ranked No. 40 on the American Film Institute's list of the 100 Greatest American Movies of All Time.

The director, who infamously took an unhealthy interest in his female stars, personally chose her costumes during a shopping trip to Bergdorf Goodman in New York City.

Saint's other prominent movies included  Exodus,   The Sandpiper  with Elizabeth Taylor and Richard Burton, and  A Hatful of Rain.  

The iconic actress marked her return to the small screen in the 70s and 80s. She reunited with her  On the Waterfront  co-star Karl Malden in the television movie  Fatal Vision  and was featured in a recurring role as Cybill Shepherd's mother on  Moonlighting.

In 2005, she was introduced to an entirely new audience for her roles in the beloved children's film  Because of Winn-Dixie  and, the following year, in  Superman Returns. 

In 2018, she made a memorable return to the screen when she presented the Best Costume Design award at the 90th Academy Awards.

Saint remained spry and nimble in her old age, telling People ahead of her 100th birthday in 2024 that she planned to celebrate the milestone number with four generations of family members.

 I certainly don't feel 100 years old,  she shared.  I continue to take walks out in the fresh air, like watching baseball - especially the Los Angeles Dodgers- and enjoy time with my family and friends. A good life. 

She is survived by her two children and four grandchildren.
