Significant Other is a 2022 American science fiction horror film written and directed by Dan Berk and Robert Olsen. The film stars Maika Monroe and Jake Lacy as a couple dealing with relationship issues while backpacking in the woods in the Pacific Northwest, whose activities are interrupted by a meteor strike bringing an evil shapeshifting alien life form into the picture, explores themes of the unknown, and the vastness of the universe, which are hallmarks of Lovecraftian stories. Though the movie is not labeled “Lovecraftian” it takes elements that draw inspiration from the cosmic horror themes associated with H.P. Lovecraft.

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.
