Why did they push this story arc to the side?
It seems like the creative team is saving a lot of Astrid drama for the what is likely an inevitable sequel. At a press conferences earlier this month in Los Angeles, producer Nina Jacobson revealed that they did film more material between Astrid and Charlie.
"We had originally shot more of them together, but what we found when we first started to show the movie to audiences was that, just in terms of screen time, the dissolution of her marriage and then the introduction of this wonderful new guy actually both got short shrift when you rushed it," Jacobson explained. "You felt like you weren't getting the strength that it took her to walk away from her marriage, but also the hope that you might feel about a new person. And that it wasn't just a rebound."
So they decided: "We'll just tease [it] a little bit at the end and hope that audiences ask for more movies so we can continue to tell the story." Director Jon M. Chu explained it was also a matter of making sure that Rachel and Astrid's storylines stood independent of the men in their lives. "This is not about getting the guy, ultimately, for both Rachel and Astrid," he said. "It's about self worth."
