The first trailer for the Michael Bay-produced live-action Teenage Mutant Ninja Turtles movie has appeared.  Unsurprisingly, it focuses on more April O’Neil, played by Megan Fox, than the turtles themselves, though they do make some brief appearances toward the end.
 
Despite the repeated delays (see "Live-Action 'Teenage Mutant Ninja Turtles' Delayed Again"), and usual  Michael Bay set-exploding action, the trailer actually appears to be staying closer to the source material than fans feared.  And Michelangelo’s sense of humor appears to be intact.
