Ever since Harry Potter hit it big, the studios have been on the lookout for possible new family fantasy franchises that will make them lots of money. Percy Jackson & The Olympians: The Lightning Thief has even gone as far as signing up the director of the first two Potter movies, Chris Columbus, for a movie about a boy who discovers he’s the descendant of a Greek god and sets out on an adventure to settle an on-going battle between the gods. While a teaser trailer has been released before, now a new promo has been unveiled, which gives us a better look at the new fantasy flick. Click below to take a look. The film is due out on February 12th, 2010.
