Daniel Radcliffe, Emma Watson and Rupert Grint Hit the Red Carpet (PHOTOS)

Just days before they appear together for the next-to-last time on the big screen, Harry Potter co-stars Daniel Radcliffe, Emma Watson and Rupert Grint gathered in London on Wednesday for a very special event related to their hugely successful movie series.

As the November 19 release date of Harry Potter and the Deathly Hallows Part 1 looms ever closer, the HP holy trinity came together at Claridge’s Hotel in London for an event to celebrate Warner Bros.’ purchase of Leavesden Studios, where the movie series is filmed. (As previously reported, the movies’ sets will be opened up for public tours in the near future.)

Hit up the photo gallery to see Watson, Radcliffe and Grint do their promotional duty. Do you think Deathly Hallows will match up to previous Harry Potter movies? Let us know in the comments section.
