It’s a coup! BQB here with a review of “Hunter Killer.”
A US sub is lost. Gerard Butler plays a sub captain sent with his crew to investigate. Shenanigans ensue. The Russian President is taken hostage by his military and if that subversion is successful, well, I don’t want to give it away but suffice it to say the stakes are high and it becomes in America’s best interests to save the Russki Prez.
The investigation mission becomes a rescue mission and it’s action galore. There are some undertones of Hunt for Red October though this film is all on its own. I’ll give it to Gerard Butler. His performance in “300” was great and after that I always thought he was kind of wooden, but he excels here as the captain who earned his stripes the hard way, by working his way up through the ranks as opposed to those who went to officer school and were awarded a high rank without getting their hands dirty.
STATUS: Shelf-worthy.

I liked this movie as well. I agree that Butler’s recent past work have been more “wooden”, but I thought he did a good job in Hunter Killer.
