It sounds like a scene from a James Bond film itself, full of mystery, intrigue and suspicion.
But when the new 007 blockbuster Spectre is released next month, cinemas across Britain will be on high alert, with security beefed up and staff donning military-style night-vision goggles to patrol the dark auditoriums in a bid to crack down on piracy.
Movie pirates are said to be resorting to increasingly clandestine tactics to avoid being caught, hiding recording devices in holes cut into popcorn cartons or covering their phones with a sock to hide the lit screen.
The film industry is determined to stop criminals intent on illegally recording the eagerly awaited new film and posting it online.
Kieron Sharp, director-general of the Federation Against Copyright Theft, which tackles piracy, said staff would be taking extra measures to catch anyone trying to make illegal recordings.
