Scene Where Claire Laughs at Christina's Wedding Vows
At Christina Cleary's wedding, she and her husband exchange vows that are cringeworthy at best, and younger sister Claire (Rachel McAdams) cannot stop laughing at this.
Watching the scene, Rachel McAdams seemed to be genuinely laughing, and I was wondering if anyone else thought that this might have originally been unscripted, but kept in the movie because it worked so well?
