Last week, BoomTown posted on the amazing number of Joker impression videos related to the hit Batman movie, “The Dark Knight,” that were popping up all over the Web.

Next up?

Well, it seems the honor will be going to Harry Potter knockoffs and tributes, due to the upcoming sixth movie in the series about the boy wizard, “Harry Potter and the Half-Blood Prince.”

The movie is set to be released Nov. 21 and focuses on the early life of evil Lord Voldemort, when he was only a creepy orphan named Tom Riddle.

Here’s a video, below, of the actual trailer, which was recently released online and is playing in theaters.

And below that is a good example of one of the many user-created videos that tout the new Potter movie by using old clips to create new trailers. None of them is sanctioned by Warner Bros. (TWX), which is releasing the movie and will not likely discourage the phenomenon, as it builds excitement for the film.
