The plot thickens when Kristen's mom and Yvette's aunt, played by Jamie Lee Curtis and Sigourney Weaver, reveal they have an even older rivalry. Add in Betty White as a hip grandma and you've got an ensemble that's ready to play.
"It genuinely is a good group of people," said Curtis. "We are, the movie is, only as good as the sum of our parts. We add up together to create something. And we all knew that going in."
"There were so many feisty women," said Bell. "This is kind of a rare script where everybody's not like unlucky in love. We really had a blast."
"It was controlled chaos. You know, at any moment there could be somebody that could upstage somebody that could upstage somebody," said director Andy Flickman. "Then there is always Betty White who'll upstage everybody. So you took the three cameras, put everything on and let the magic unfold."
And with White on board, you can count on plenty of magic.
"She's a machine. She just keeps going and going and never complains," said Yustman. "She is such a trooper and so funny. I can't even handle it."
"She was the funniest person in the room and so professional," said Bell. "I'm surprised she had time to slot us into her busy schedule. She works more than all of us combined."
"You Again" is rated-PG and is in theaters this weekend.
