Diane Lane isn’t a fan of her son’s new girlfriend in the first trailer for Lionsgate’s Anniversary. Directed by Jan Komasa, the thriller also stars Kyle Chandler, Dylan O’Brien, Phoebe Dynevor, Madeline Brewer, Zoey Deutch, Mckenna Grace and Daryl McCormack.

In Anniversary, a close-knit family is caught in the turmoil of a controversial rising movement known as “The Change.” Ellen and Paul (Lane and Chandler) witness their lives fall apart when Ellen’s former student Liz (Dynevor) reappears and starts dating their son (O’Brien). As Liz becomes a part of the Taylor family, tensions rise and loyalties are tested. Liz’s role in “The Change” brings simmering conflicts to the surface, unravelling the fabric of the family just as the nation itself stands on edge during an alarming and challenging time of uncertainty. Now why does that sound familiar?

“Our son’s new girlfriend is a former student,” Lane says in the trailer. “She’s radical in her ideology… I don’t think it’s a coincidence that she’s attached herself to Josh.”

Komasa helms the film from a script by Lori Rosene-Gambino, itself from a story by Komasa and Rosene-Gambino. Serving as producers are Nick Wechsler, Steve Schwartz, Paula Mae Schwartz and Kate Churchill.

Anniversary will be released in cinemas on October 29th, 2025. Watch the trailer below:
