Are you getting excited for "Harry Potter and the Half-Blood Prince" yet?

Expected to challenge "Transformers: Revenge of the Fallen" for the summer box office crown, Warner Bros. is starting to release more and more footage from the sixth "Harry Potter" flick.  And just in time for the Memorial Day weekend, the studio had made two major new clips available to view.

First up, an extended clip showing the after affects of some magic candy Ron Weasley (Rupert Grint) eats off the bed of roommate Harry Potter (Daniel Radcliffe).  Needless to say, for those who haven't read the J, K. Rowling's novels, the scene brings Ron's character to a new, hum, high.

Also for your pleasure, a fantastic new featurette on the relationship between Dumbledore (Michael Gambon) and Harry that features enough new scenes from the movie to pretty much qualify as a trailer.

Check out both clips below.

"Harry Potter and the Half-Blood Prince" opens nationwide on July 15.
