The sequel to 'Something Borrowed,' titled 'Something Blue,' hasn't officially been confirmed as a film yet, but if it follows the book by Emily Giffin, we'd likely see a shift in focus. Kate Hudson's character, Darcy, takes center stage in the novel, so she'd probably return alongside Ginnifer Goodwin's Rachel. John Krasinski might reprise his role as Ethan too, given his pivotal arc in the books.
Honestly, I'd love to see the dynamic between Darcy and Rachel explored deeper—their friendship was messy but compelling in the first film. The original cast had great chemistry, so I hope they'd all come back. Maybe they could even add some new faces to spice things up, like a love interest for Darcy or Ethan. Fingers crossed for an announcement soon!
