Under Siege (1992)

At first glance Under Siege may seem to depart from the Seagal formula, but I assure you it does not. It follows the two word title rule well, and the lack of Seagal holding a gun on the poster is made up for by making his head take up roughly 30% of the poster (and another 50% by his shoulders). Seagal plays a cook in this movie, but he's a cook who used to be a Navy SEAL, so the character rule is covered. On the boat where Seagal cooks the captain is killed (by terrorists) and the ship is taken hostage and Seagal must kill a shitload of people to get the ship back!
