3/5 Lawrence as a knight of today and yesterday
  by Jim Gateley (Sunnyvale, CA)
3 of 5 stars for the comedy movie Black Knight. A worker (Martin Lawrence) in a medieval theme park finds himself transported back in time to the 1300's (Middle Ages) after getting a bump on his head. Finding himself between several factions and even a plot to overthrow the king, our hero "Skywalker" even has a beautiful maiden to rescue.

Well photographed, well written and pretty funny at times, this movie is easy on your brain and entertaining. Lawrence is good and fun to watch. Yes, this is a good movie and worth watching.

5/5 A Laidback movie!

Martin Lawrence plays as an Renaissance Fair like amusement park employee, accidentally falls in the fake moat at work reaching for a glowing medallion necklace. He is magically transported back to the late 14th century believing he is at the new Castle World opening down the road. Later realizes this is no park and he helps return a queen to her rightful throne. We enjoyed this movie, it is very funny.

1/5 Martin proved the three stikes your out rule with this horrid film

There once was a comedian named Martin Lawerence who had a string of flops begining in the year 1999 with the piece of rubbish Blue Streak. He struck out again with What's The Worst That Could Happen and in 2001 he made Black Knight. Black Knight is full of bad acting, cliched jokes and it's boring. Martin made another stinker later in the year called National Security and wouldn't reedem himself until Bad Boys 2 in the sunmmer of 2003. It should be noted that Chris Tucker wisely turned down the lead role.
