Despite a cast including Rihanna, Alexander Skarsgard, and Brooklyn Decker, the film which was loosely based on the board game of the same name was a total failure. Considered to be one of the worst Naval films of all time, the movie cost the studio about $220.4 million in losses.
Conan the Barbarian (2011)
It seems like Hollywood will never learn when it comes to reboots. Although Jason Momoa gave a valiant effort, critics concluded that Arnold Schwarzenegger set the bar for this role. The reboot ended up losing somewhere between $60 and $66 million.
