As of late 2026, there are no confirmed announcements or credible records regarding a feature film titled "Tantalum" scheduled for release. The provided knowledge base details various other productions from the same year, including the Thai horror movie "Stain," the Thai drama "Shadow Sisters 2026," and the Indian thriller "Toxic: A Fairy Tale for Grown-ups," but does not contain information about a movie with this specific title.
Consequently, no plot summaries, cast lists, production facts, or reception data can be generated for this film without fabricating information. It is possible that the title may refer to an unreleased project, a working title, or a confusion with another similarly named work, such as the science fiction novel "The Three-Body Problem" series which involves elements of nuclear physics, or potentially a short film not widely documented in mainstream databases.
Due to the lack of confirmed information regarding a 2026 film titled "Tantalum," it is currently unavailable on any streaming platforms, rental services, or theaters.
