The 2013 Keanu Reeves' movie 47 Ronin was a $175 million disaster and his biggest box office bomb so far. It combined Western action and fantasy tropes with a Japanese historical samurai narrative based on the "Legend of the 47 Ronin," wherein 47 elite samurai assumed ronin status after Lord Asano was betrayed and forced to perform seppuku, resulting in the masterless warriors seeking revenge for their fallen lord by battling a powerful witch, supernatural armies, and mythological creatures. Eventually, their bravery, loyalty, and fighting prowess not only bring them victory but also restore their honor.
