In The Bluff, Priyanka Chopra Jonas stars as the former pirate legend called Ercell "Bloody Mary" Bodden. Ercell has tried to outrun her past and her nasty ex-captain (played by none other than Karl Urban), but now she must kick pirate ass to protect her family. I'm here for it!

Flowers, with a script by Flowers and Joe Ballarini, and it promises bloody brawls, rapscallion sword fights, and general backstabbing on the high seas and on shore. — S.C.
