Percy Jackson & the Olylmpians: The Lightning Thief
You go years without seeing Medusa and then all of a sudden we get two in one week. Percy Jackson is a descendant of both mortals and greek gods, and apparently his lineage comes with some way cool powers and some fearsome villains who want to do him in (among which is Uma Thurman as the aforementioned Medusa). Based on a series of books and directed by Chris Columbus, who helmed the first two Harry Potter films, this looks like it could be some good escapist teen fun, though not quite on the same level as Harry Potter. Watch for this on February 12.

Clash of the Titans
As for Medusa number two, she is just one of the monstrosities in this remake of the 1981 film about the adventures of Perseus from Greek mythology. Most of the original film's charm comes from the stop-motion effects by Ray Harryhausen, so it will be interesting to see how well the ideas translate to modern effects technology. The clash begins on March 26.

Remember Me
Robert Pattinson plays the tortured emo kid card once more in this drama about a young man trying to find his way. He's really got the angry young man thing down and Lost's Emile de Ravin makes for an appealing romantic interest. This will be out on March 12.
