Find Scares and Sci-Fi in Significant Other

When a young couple goes backpacking deep in the woods of the Pacific Northwest, their love will not be enough to save them. Significant Other focuses on Ruth, who seems to have survived an accident as the movie begins. As she refuses to recount what happened, it seems like she may be hiding an even more important -- and dangerous -- secret. Significant Other appears like a traditional horror/ thriller, and the dark forest is the perfect setting for a host of scares. However, there's something more fantastical at the heart of the movie, and not all of Ruth's secrets may be as mundane as murder.

Significant Other premieres Oct. 7 on Paramount+.

Guardians of Time Delivers Classic Fantasy

Guardians of Time presents a classic fantasy tale: four kids who find a magical world hiding in their house end up lost in this new land.

For genre fans eager to see all the things that made them fall in love with fantasy in the first place, however, Guardians of Time will be right up their alley.

Guardians of Time premieres on DVD, digital, and on-demand Oct. 11.
