Continuity mistake: Near the end of the movie, Spock, with a phaser in his right hand, is chasing Kahn across the urban landscape. Kahn jumps onto a departing garbage scow and with a mighty leap, Spock jumps towards the bottom of the scow and is then shown holding on with two (empty) hands. A moment later, he is shown climbing onto the deck of the vessel, with the phaser back in his hand. Kahn kicks the phaser away and it disappears once again, this time over the side.
