After a two year break Harry Potter and company are back for their sixth adventure "Harry Potter and the Half Blood Prince". The film based on the next to last book in the legendary series has the teen wizard finding that the Hogwarts Academy is no longer the safe haven it once was and that he needs to prepare for what's likely to be a final showdown with the forces of evil. That's not the only magic going on. There's also magic of the romantic sort for the maturing young wizard. Romance also blossoms at a greeting card company in the comedy "(500) Days of Summer". Summer's not just a season, it's also the name of Zooey Deschannel's character, a woman who doesn't believe in romance. That doesn't stop her ultra-romantic co-worker Mark, played by Joseph Gordon Levitt, from falling hard for her on her first day at work. His challenge is convincing her that they're true soul mates. "(500) Days of Summer" is rated PG-13.
