Lie detector hire for film and drama
Lie detector hire for film is different from hire for a format. On a scripted production the instrument is in shot, so it has to behave like an instrument: the pens must move for real and the traces have to survive a close-up.
Why the analogue rig usually wins
Ink on rolling paper photographs in a way a laptop screen cannot. It fills a frame, it moves, and an audience recognises it instantly without a line of dialogue explaining what they are looking at.
For a scene set before the 2000s it is also the only accurate choice. A modern sensor box in a period scene is the kind of detail that pulls an audience out of a film.
On-set consultancy
Someone has to sit with the director and say which questions would genuinely deflect a trace, where a cutaway breaks continuity on the chart, and what an examiner would actually do in the room.
That advice is what separates a polygraph scene that convinces from one that does not, and it is why productions book a consultant rather than sourcing a prop.
Questions we get asked
- Can you supply a period-accurate polygraph?
- Yes. The analogue instrument — pens, moving chart paper and ink — is the machine most audiences picture, and it is correct for scenes set from the 1950s onwards.
- Do you advise on the script?
- We advise on the polygraph sequences: what the instrument would realistically show, what an examiner would say, and what would look wrong to anyone who has taken one.
