Tonight, entertainment television series Extra will be showing the first trailer for Harry Potter and the Prisoner of Azkaban. The show will also be broadcasting an exclusive on-set report on tomorrow's episode.
Lisa Phillips, director of publicity for the show, confirmed the segments for HPANA this afternoon. "Today we have the world premiere of the trailer, and tomorrow an exclusive on-set report," she said.
Apparently one of the Extra reporters is a huge Harry Potter fan and was able to secure the rights to broadcast the trailer. His on-set report will be airing tomorrow night. Check your local listings for show times! (Extra's site also has a local listings lookup.)
