 It is often claimed that this is the only Star Trek film where no  weapons are fired. This is incorrect, as Kirk uses his phaser to  weld a door shut, and the whaler fires its harpoon. Chekov also  tries to use his phaser, though it doesnt work. It is also one  which no cast member from this film is killed, as the only deaths  were from the reused footage from  _Star Trek III: The Search for Spock (1984)_ (qv).
