At the end of Olivia Wilde‘s latest film The Invite, before the credits roll there is a brief moment when the screen flashes to a note that reads “For Diane.”

The Diane is mention is Diane Keaton, and Wilde has dedicated the movie — which follows a couple barely keeping their marriage together who invite their neighbors over for a quickly detailed dinner party — to the late star.

“I really wanted to show this movie to Diane. I don’t think that there is an Invite without Diane Keaton because she’s in so many of the films that inspired this film,” Wilde told The Hollywood Reporter at the L.A. premiere on Wednesday. “She is the first actress I recognized to kind of represent a totally unique and complex woman; she didn’t fit any archetype, she was singular in her vulnerability, her complexity, her creativity. She’s unlike anyone else and she was very encouraging to me personally, and I just wanted this to be for her.”

Keaton, who passed away in October, played Wilde’s mother in the 2015 comedy Love the Coopers. When she died, Wilde penned a long tribute on Instagram, recalling how “she laughed through night shoots, kept us roaring with laughter constantly actually, and talked to us for hours about love. She told me to keep my heart open. She told me to direct. She told me to be brave. She told me to keep laughing.”
