John McClane's Grenade Launcher

This "Chinese" grenade launcher was screen-used by Bruce Willis as "John McClane" in the alternate ending for DIE HARD WITH A VENGEANCE. Made from cast iron and very heavy, this is the only launcher used in this scene. The inside is hollow where a "charge" was placed for the explosion that killed Simon Gruber (Jeremy Irons).

In the alternate (original script) ending, Simon Gruber manages to escape and smuggle the gold out of the country by melting them into little Empire State Building miniatures painted in silver. The alternate ending is set a few years after the heist. John McClane has been fired from the NYPD after more than 20 years in the force and even lost his pension due to the FBI's suspicion in his involvement with the heist. McClane finally manages to track Gruber down at his hideout in Nova Scotia and confronts him quietly inside a bar during the day. He tells Gruber about how he has figured everything out and takes out an Empire State Building miniature to show him. He then forces Gruber to play a Russian Roulette game called "McClane Says" with this Chinese grenade launcher that looks identical on both ends. Gruber loses and dies.
