You're gonna LOVE this! In "Black Knight," Martin Lawrence works at a castle-themed amusement park, and he falls into the moat, and when he comes up out of the water, he's back in medieval times! And it's all wild and crazy because, you know, he's this modern guy -- and he's black! -- and he's back in the time of knights and stuff! And of course, you know Martin Lawrence: He's so crazy all the time! And so of course the medieval people are, like, "Who's this guy? Why is he dressed so funny?" But then the amazing twist is that he uses his modern knowledge, like of football and stuff, to help his medieval friends win a battle. Can you believe it? And it's all so funny 'cause, you know, Martin Lawrence is --

Grade: F

Rated PG-13, some profanity, some sexual innuendo
