Hanging By a Wire review – cable car rescue documentary dangles viewers on the edge of disaster

The extraordinary fate of eight people trapped above a chasm in Pakistan makes for a tense, skilfully assembled survival story with unexpected flashes of comedy

Survival documentaries are a weird little genre of nonfiction film-making that recount the stories of accidents and natural catastrophes – and more often than not, the daring rescues of people caught up in them. Eyewitnesses and the loved ones of those endangered are top of the interview list, to keep the sense of danger and emotional stakes at the top of everyone’s mind. Survivors can also have their say, and more adventurous film-makers might care to recreate the action with actors or the actual survivors themselves.

This account of how eight people – six teenage boys and two adult men – were left suspended over a chasm in northern Pakistan in 2023, when a wire on the cable car they were travelling on broke, is a pretty conventional example of the form. For obvious reasons, no one tries to recreate the situation, but since it was quite recent there is no shortage of news footage and amateur clips to fill out the particulars. The downside of doing a story that’s so recent is that some of the audience may remember what happened anyway, but still there’s plenty of nail-nibbling suspense here, and sequences that will give anyone with acrophobia the heebie jeebies – especially the drone shots that zoom close on the terrified faces of those trapped inside the dangling car.
