大列車強盗
The general fear of premature burial led to the invention of many safety devices which could be incorporated into coffins. Most consisted of some type of device for communication to the outside world such as a cord attached to a bell that the interred person could ring should they revive after the burial. A safety coffin of this type appears in the 1978 film "The First Great Train Robbery", and more recently in the 2018 film "The Nun". Other variations on the bell included flags and pyrotechnics. Some designs included ladders, escape hatches, and even feeding tubes, but many forgot a method for providing air.
