Talk:Harry Potter and the Deathly Hallows: Part 1

Why is there a colon in article title?
The actual title for the movie is "Harry Potter and the Deathly Hallows Part 1". There is no colon anywhere that I can see, particularly not in the movie title screen, the title on the poster, the title on the bottom of the poster in the cast billing area (for better view see http://www.themaxonline.net/wp-content/uploads/2010/11/harry_potter_and_the_deathly_hallows_part_1_movie_poster2.jpg), or in the end credits of the movie (see http://i51.tinypic.com/2cekbp4.jpg). So I don't see why it should be written that way, and I think it should be changed.
