The new trailer for "Mirror, Mirror," sets up an intriguing 2012 duel over Snow White movies. MM, with a cast that inclues Julia Roberts and Nathan Lane, is a comic romp.

The other big screen treatment is "Snow White and the Huntsman," starring Kristen Stewart and Charlize Theron. Its trailer promises a dark, dark Star Wars-like saga of deathly intrigue.

They couldn't be more different, thankfully. So there will be one option for the day you're baby-sitting your niece and nephew, and another for date night.
