This tries to be like Lock Stock with lots of interplay between a multitude of characters. The main guy is an American Nigerian stranded in Mexico. There's an unscrupulous boss played by someone who is in a lot of films recently but I can't recall his name (Eggard? Eckhardt?). Charlize Theron comes on the back of an excellent performance on Youtube Hot Ones to play the other boss, willing to stab he-who-can't-be-remembered in the back...and there are wives, kidnappers, criminal kingins and cops.
I only watched this to kill some time, I'd expected terrible and didn't get it, but I didn't get great either.
