Significant Other is a 2022 American science fiction horror film written and directed by Dan Berk and Robert Olsen.

In September 2021, Paramount Players won a bidding war for the film, with Monroe and Lacy already attached to star, and Berk and Olsen to direct. The film was released on the streaming service Paramount+ on October 7, 2022.
