Under Siege (1992) - 5 major mistakes

Continuity: In one sequence (in which Ryback tries to save the drowning sailors), Ryback is running with two machine guns and kills a bunch of bad guys, including one guy with a moustache and cap who falls down a flight of stairs. After the machine guns are empty, he pulls out a pistol, slowly goes into another room and, surprise! the same guy appears, gets shot and falls down the stairs! Its obvious they ran out of guys to kill in the film, so they just ran the same film twice to look more violent.

Continuity: When Erika Eleniak and Steven Segal walk through the battleship and talk about her rule, ie. not killing people and not dating musicians, Steven has different types of the SMG MP5 in his hands. He changes from MP5 to MP5K and back in the blink of an eye.

Continuity: The big black terrorist who always accompanies Stranix loses his grey waiter jacket when he and the other terrorists are herding the Missouri crew into the makeshift prison. You can see this clearly when he shoots a marine prisoner who tries to overpower him. Later, when he follows Stranix into the captain's office, he is wearing his waiter jacket again.

Visible crew/equipment: Near the end of the film the prisoners are released. When the door opens water comes gushing out followed by 3 prisoners. You can see the water slide that the prisoners have slid down.

Continuity: Near the end of the movie, when Stranix launches the two tomahawk missiles toward Hawaii, look closely at where the missiles are launching. they're firing out of the space between the two ABLs (Armored Box Launchers) instead of from inside the launchers.
