Directed by: Paul Feig
Starring: Anna Kendrick, Allison Janney, Blake Lively
Character mistake: Michele Morrone, who is a native Italian speaker, badly flubs his line in Italian when he is supposed to reassure Matteo about no photos being taken at the wedding. It's by all means 'a bad take.' (00:29:55)
Character mistake: The end credits list one of the songs as "Score from Un Poste Al Sole." It is a misspelling. It refers to something played by the hotel TV inside Margaret's room, an Italian soap opera called "Un posto al sole," with an "o." (01:59:25)
Audio problem: At the wedding bar counter, Sean talks to Stephanie about how toxic the ex's resentment is. Stephanie responds and looks toward Blake Lively and her family. In the following cut, the characters are silent, but you can see Henry Golding from behind moving his jaw as if he's speaking. (00:27:55)
Sean Townsend: Stephanie, listen to me. If a grudge is self-inflicted poison, then the person who invited you to this wedding is the most poisoned person that I have ever met. She doesn't let go, and you are the biggest grudge of her life.
