After the event, Katherine took to her Instagram to reflect on her first time at TIFF.

“Last night was unreal..✨✨ Three years ago I came to TIFF with my agents – I was filming my first project and no one knew who I was – and I remember standing outside, behind the barricades at the Princess of Wales theatre, watching Matthew McConaughey and Scarlett Johansson attend the premiere of the big film for that year…I remember thinking to myself, ‘How incredible would it be to have a film here one day?’” Katherine wrote.

She continued, “Last night, as we pulled up to the theater, I saw the exact spot where I was standing three years ago, and got to experience my first film festival premiere at that same theatre. Thank you so much to everyone who came out last night for making this screening so special ❤️ and thank you to @lionsgate and @riancjohnson for having me be a small part of this film amongst this amazing cast 🔪 #tiff #knivesout”

Later in the day, Katherine and Jaeden celebrated the film’s debut at the Hollywood Foreign Press Association and The Hollywood Reporter Party party at the Four Seasons Hotel.
