Circle of Iron (1978) Coming to 4K UHD from Blue Underground in 2026
Blue Underground has announced that Circle of Iron (1978), also known as The Silent Flute, will be coming to 4K UHD in 2026. This marks the label’s return to the title after previously releasing it on Blu-ray in 2009. The new edition features a brand new 4K restoration sourced from the original camera negative, along with Dolby Vision HDR and Dolby Atmos audio.
The martial arts fantasy film is based on a story conceived by Bruce Lee, James Coburn, and Stirling Silliphant, and stars David Carradine in four roles — including “The Silent Flute,” the blind martial artist who guides the protagonist. Roddy McDowall, Eli Wallach, and Christopher Lee also appear in supporting roles. No bonus features, packaging details, or exact release date have been provided yet. We will update this article when we know more.
