‘She Loved Blossoms More’ (2025)

In theaters on October 3, 2025, and also available the same day on digital platforms, ‘She Loved Blossoms More’ follows three brothers who construct a makeshift time machine to bring their late mother back, only for their estranged father’s return to twist their experiment into a nightmare. The project is directed by Yannis Veslemes, from a script by Veslemes and Dimitris Emmanouilidis.

The cast features Panos Papadopoulos, Julio Giorgos Katsis, Aris Balis, Alexia Kaltsiki, Sandra Sarafanova, and Dominique Pinon. Festival synopses highlight the grief-driven science, an antique wardrobe turned temporal conduit, and escalating body-horror imagery that pushes the family’s fragile bonds to the breaking point.

‘My Hero Academia’ (2016– )

New episodes begin October 4, 2025 on Crunchyroll as the anime continues its endgame arcs, bringing the Heroes and Villains into a final, large-scale confrontation that spans multiple fronts. Studio Bones leads production.

Key staff include chief director Kenji Nagasaki and series director Naomi Nakayama, with character designs and action supervision continuing under Bones’ veteran team. The returning Japanese voice cast includes Daiki Yamashita as Izuku “Deku” Midoriya, Nobuhiko Okamoto as Katsuki Bakugo, Ayane Sakura as Ochaco Uraraka, and Kenta Miyake as All Might, as the story pushes toward the resolution of Deku’s battle with Tomura Shigaraki and All For One.

‘Primitive War’ (2025)

Streaming on October 3, 2025 via Fandango at Home, ‘Primitive War’ adapts Ethan Pettus’s 2017 novel about Vulture Squad, a U.S. recon unit sent into a Vietnam valley to find a missing Special Forces team and stumbling into a kill zone populated by de-extinct dinosaurs. Luke Sparke directs from a screenplay by Sparke and Pettus.

Ryan Kwanten, Tricia Helfer, Nick Wechsler, Jeremy Piven, Anthony Ingruber, Aaron Glenane, Carlos Sanson, Albert Mwangi, and Adolphus Waylee headline the ensemble. Story materials point to Cold War tinkering—time displacement and wormhole fallout—as the origin of the prehistoric fauna, with Frederik Wiedmann scoring and Wade Muller handling cinematography.

‘Jimmy and Stiggs’ (2025)

Available September 30, 2025 on Fandango at Home and Apple TV, ‘Eli Roth Presents: Jimmy and Stiggs’ is a sci-fi horror comedy about out-of-work filmmaker Jimmy Lang, who insists he’s been abducted by aliens and recruits his friend Stiggs Randolph to prepare for their return—igniting one very chaotic night. Joe Begos writes and directs.

The film stars Matt Mercer as Stiggs and features a practical-effects-forward approach that leans into hallucinatory creature work and midnight-movie energy. Producer credits include Joe Begos, Josh Ethier, Matt Mercer, Josh Russell, and Sierra Russell, with a narrative that blends abduction lore, DIY paranoia, and escalating cosmic weirdness.

‘Affinity’ (2025)

Dropping September 30, 2025 across digital retailers including Fandango at Home and Amazon Video, ‘Affinity’ centers on Bruno, an ex-Navy SEAL haunted by PTSD who rescues a mysterious woman and assembles an elite team after she is abducted, uncovering a bio-engineering conspiracy. Brandon Slagle directs.

Marko Zaror leads the cast, joined by Louis Mandylor, Brooke Ence, Jane Mirro, and Brahim Chab. Official summaries outline Bruno’s Thailand-set history, tactically driven retrieval missions, and a science-thriller thread tied to engineered enhancements, with Well Go USA handling U.S. distribution.
