A lethal Brick Joke
. Where the means of a character's demise is set up early on, but the actual death occurs much later in the story. May involve a Chekhov's Gun
, but some additional action is required - someone must attempt to fire it when it is introduced, so to speak, with the results not evident until later. If the means of death is merely introduced early and used later (i.e. someone is given a weapon at the beginning of the story, but doesn't use it until much later) then it's a Chekhov's Gun
- The Rocketeer. The rocket pack is hit by a bullet early in the film, but the bullet hole is patched with gum and no further note is made of it... until the hero removes the gum before giving the pack to the Big Bad, with predictable results.
