It’s July tomorrow, which means the last phase of Warner Bros.’ year-and-a-half long advertising plan for Harry Potter and the Half-Blood Prince goes into effect.  That means lots of talk show appearances, preview screenings, and other scheduled events Potter-philes might want to write down.

For example: soon, HBO will start airing a 13-minute Harry Potter and the Half-Blood Prince “First Look” featurette.  Since it’s 13 minutes and used to pad time after movies, the scheduling is a bit all over the map.  Here are the first few days and times:

Fri 7/3 09:45 PM HBO - EAST
Sat 7/4 12:45 AM HBO - WEST
Sat 7/4 12:00 PM HBO - EAST
Sat 7/4 03:00 PM HBO - WEST
Sat 7/4 06:40 PM HBO FAMILY - EAST
Sat 7/4 09:40 PM HBO FAMILY - WEST
Sun 7/5 05:45 AM HBO FAMILY - EAST
Sun 7/5 08:45 AM HBO FAMILY - WEST

Head to HBO’s website for a full schedule.

Also coming up: Daniel Radcliffe and Emma Watson are doing the Late Show with David Letterman.  Emma will appear July 7th (Tuesday), and Dan will appear July 8th (Wednesday).
