Iron Lung

No LGBTQ+ characters appear or are identified. The narrative centers on a solitary convict and a distant radio contact, with no romantic or same-sex relationships depicted on screen.

The protagonist is a man. The only other named character is a woman heard over the radio; she issues instructions but never appears on screen or drives the physical action.

The cast is predominantly white, including Mark Fischbach and Caroline Kaplan. No characters of color appear in significant roles, and the desolate setting offers no context for racial diversity.

The film portrays a bleak, post-apocalyptic future where humanity is nearly extinct. Authority figures are distant and punitive, sending a convict on a dangerous mission with little regard for his safety.

No characters with physical or mental disabilities are depicted. The protagonist’s claustrophobia is a source of fear but is not framed as a disability or explored with depth.
