A predictable vehicle for the resistable Martin Lawrence, Black Knight is yet another rerun of Mark Twain's Connecticut Yankee at the Court of King Arthur concept which here plays like a horror-free, considerably less funny take on Army of Darkness. Jamal (Lawrence), minion in a mediaeval theme park, reaches into a moat for a magic amulet and is transported to the 14th century, where he is appalled by the toilet facilities, pals around with a disgraced knight (an equally disgraced Tom Wilkinson), romances a feminist lady-in-waiting (Marsha Thomason), introduces soul music to the court in a bit done better in A Knight's Tale, and becomes the legendary black knight to help the rebels overthrow the wicked king. It has a bigger, more lavish feel than most of Lawrence's makeshift knockabouts, but that may also be why it is even less funny, since his rants are rather reined-in and his screen character comes across as just overly pleased with himself rather than a comic foul-up who turns heroic. --Kim Newman

No-one tries very hard in Big Momma's House so your enjoyment of this Martin Lawrence vehicle pretty much depends on how much amusement you are able to derive from a guy dressed up as a very ample woman. The setup is of the eye-rolling, only-in-Hollywood nature: Lawrence, as detective Malcolm Turner, is after a killer, and apparently the only way to capture him is to pose as the bad guy's ex-girlfriend's grandmother, who--the film cannot stress this point too much--is quite large. Apparently, Sherry (Nia Long), the young woman in question--she's as attractive as Big Momma is, well, you know--is none too bright, for she falls for Malcolm's ruse, which of course ostensibly amuses mainly because it's so transparent. Paul Giamatti is wasted as Malcolm's partner, while director Raja Gosnell's clunky sense of comic rhythm is bewildering, because he used to be an editor (he brought a similar lack of magic to Home Alone 3). Eddie Murphy in The Nutty Professor 2: The Klumps is far more accomplished, versatile and funny. --David Kronke
