Yes, this is not an original concept. There has been many movies about submarines trapped in deep water before in the battle for survival. However, none of them starred Gerald Butler, who is back in top form as the submarine captain. The movie also have solid supporting casts in the forms of Oscar winner Gary Oldman, Common, and Linda Cardellini to make the movie more exciting to watch. Not all the action took place strictly inside the submarine. It split equally in the Pentagon war room, at the Russian Naval base, in the woods, and out in the open sea. Hunter Killer is a solid entertainment with good acting and many suspenseful moments that will keep your eyes glued to the screen throughout.
