Because Woody Allen doesn't get into motivation or background of a character when he's directing actors, Cate Blanchett and Sally Hawkins got together and invented the background for the sisters' relationship. So every scene when they talked about their past, although it's vague on the script and for the viewer, they both knew exactly what the sisters are talking about.
Cate Blanchett (Jasmine Francis) studied the 60 Minutes (1968) interview with Ruth Madoff, the wife of disgraced Wall Street swindler Bernie Madoff, to emulate certain vocal inflections and body language that Ruth displayed in order to capture the essence of a woman whose once wealthy and privileged world comes crumbling down around her.
In Sophia Loren's memoir "Yesterday, Today & Tomorrow: My Life", the screen legend reveals that she still absorbs inspiration from other actors to enhance her own acting portrayals, saying, "Recently, I was struck by the last scene in Blue Jasmine (2013), where Cate Blanchett has an expression on her face I'd never seen before. That expression crept inside me, and it lies there waiting to germinate a new plant, a new flower."
Cate Blanchett and Sally Hawkins were the only members of the cast to have the complete script during filming. This is not surprising, given that Woody Allen tends to keep his story lines secret, even from the cast.
Louis C.K. originally auditioned for the role of Augie, eventually played by Andrew Dice Clay. Woody Allen felt that C.K. was too nice to play the role and offered him the role of Al Munsinger instead.
Dr. Flicker, the dentist and employer of Jasmine in the movie, is a recurring character in Allen's films. Most notably, he is Alvy Singer's childhood doctor, featured in the first flashback of Annie Hall (1977).
After Cassandra's Dream (2007), this was Sally Hawkins' second collaboration with Woody Allen. She received a total of 25 award nominations for her performance in this film, including her first Oscar nomination.
The character of Jasmine Francis (Cate Blanchett) is based on Ruth Madoff, wife of Wall Street swindler Bernie Madoff. After Madoff's Ponzi scheme collapsed in 2008, he was sent to prison. Ruth Madoff moved to Boca Raton, Florida, where she lived in a condo with her sister, Joan Ramon, and Ramon's husband, both of whom had been victims of Bernie Madoff's swindle. After losing millions, Ramon and her husband were operating a car service to make ends meet. Also, like Jasmine, Ruth Madoff became estranged from her two sons, who had reported their father's Ponzi scheme to the SEC. While one of her sons, Mark, committed suicide in 2011, Ruth eventually reconciled with her other son, Andrew, and he provided a house for her to live in Old Greenwich, Connecticut.
Woody Allen's third film with a 2.35:1 aspect ratio, after Manhattan (1979) and Anything Else (2003). Unlike those films, which were shot with anamorphic lenses, this was shot with spherical lenses in Super 35.
