Speaking to ET Canada at the press junket for the ensemble comedy The Big Wedding last week, Katherine explained that she was very nervous about accidentally hitting co-star Robert De Niro as they filmed several scenes that involved her character slapping the two-time Oscar winner.
She also spoke about her own wedding experiences and joked about her protective instinct as a parent, especially now that her eldest daughter Naleigh has started pre-school.
CNN caught up with Diane Keaton, Ben Barnes, director Justin Zackham and Katherine to talk about how the cast bonded during the filmmaking process.
Katherine and Ben also sat down with SheKnows to talk about favorite moments with their fathers and wedding day disasters!
The Big Wedding was filmed in Connecticut, Katherine explained to Made In Hollywood, adding the cast had such a great rapport that after shooting had ended for the day they would all hang out at her house.
