Character mistake: In the pre-credits sequence, when Bond is fighting the Soviet troops who are attacking him, Bond hooks a grappling hook onto the back of a Soviet soldier who is a riding an snowmobile, which sends the soldier flying off the snowmobile and hanging over an icy ledge. The soldier then says "Pomageete! Roger Moore pomageete!" which is Russian for "Help! Roger Moore help!" (00:03:05)
Character mistake: When Bond and Stacey are in the file room in San Francisco City Hall, Bond pulls out the Division of Mines Paperwork on Zorin's wells and it has "HAYWOOD" written across it. The actual fault is spelled "HAYWARD." (01:21:40)
Chosen answer: Zorin is a psychopath. He may have meant it when he told May Day he loved her, or he may have just been telling her what she wanted to hear. Either way, when he thinks she'll drown in the mine as well, he doesn't consider it worth scrapping the plan just to save her. Once she escapes and has the bomb, he looks shocked partially because she wasn't killed but mostly because she's chosen to sacrifice herself to thwart his plans, something that a self-interested psychotic personality can't comprehend.
