It’s been a couple of days since I saw the latest Harry Potter movie, the one with a title so long I’m even more tired of typing it than I am of trying to figure out what the hell it even means (Deathly Hallows? I know it refers to the three brothers who made wishes and got stuff, but if we’re using hallow as a noun here it means “a saint or holy person.” So how are the brothers holy, and if they are, how are they deathly holy? And what other names in the series sound good but make no sense?) Anyhow, I keep seeing the various HARRY POTTER stars pop up on TV and make unexpected appearances in trailers for movies that are not HARRY POTTER. Earlier this week a very energetic and refreshingly down-to-earth Daniel Radcliffe was on “The Daily Show with John Stewart,” promoting his current gig as the star of the Broadway show “How to Succeed in Business Without Really Trying” (in which he sings and dances and talks with an American accent). Tom Felton, who plays Harry’s nemesis, Draco Malfoy, showed up in the trailer for RISE OF PLANET OF THE APES, which ran, coincidentally, before HARRY POTTER.
