With the U.S. release of the "Harry Potter and the Half-Blood Prince" DVD just three weeks away, a plethora of videos as well as interviews has hit the web.

Chris Columbus hasn't worked on the "Harry Potter" movies for many years but in a new interview for his newest movie, "Percy Jackson & the Olympians: The Lightning Thief," Columbus has a few things to say about the actors and that it has "been a joy to watch Daniel Radcliffe, Emma Watson and Rupert Grint graduate to bigger and better things."
