Let's sum this up in one word: finally. Warner Bros.' adaptation of J.K. Rowling's penultimate Potter novel was originally scheduled to be released last fall, but the studio moved the flick to this summer for strategic financial reasons. Furious fans protested with petitions — and pranksters mocked their outrage with viral videos, including one that cast Hitler, in his bunker scene from Downfall, going apoplectic over Potter's delay. But at last, the wait will soon be over.

''You know the headline on this one, of course,'' says Robbie Coltrane, a.k.a. Hagrid, of the franchise's sixth installment. SPOILER ALERT! ''It's the one where Dumbledore [Michael Gambon] pops his claws.'' (If you're not hip to Coltrane's lingo, well...mystery preserved.) END OF SPOILER ALERT! It's also the one where we learn Voldemort's origin story — although there's much less of it in the movie than in the book, where Harry and Dumbledore jump into pools of liquid memory to observe the bad guy's evolution. Citing the need for narrative economy and dynamic drama, screenwriter Steve Kloves says he chose ''a few key memories instead of attempting to include all of them.''

Half-Blood Prince also emphasizes Harry's relationship with Professor Slughorn (Jim Broadbent), the Potions teacher who holds a secret to Voldemort's past, plus teen-romance intrigue involving Harry (Radcliffe) and Ginny (Bonnie Wright), as well as Ron (Grint), Hermione (Watson), and newcomer Lavender Brown (Jessie Cave). ''The last film was quite intense with all that battle stuff,'' says Grint. ''This one is a lot lighter and much funnier.'' Not that the film lacks thrills. ''I worked with a giant spider,'' says Broadbent. ''Bloody marvelous.''

Starring: Joseph Gordon-Levitt, Zooey Deschanel
Directed by: Marc Webb
Release date: July 17

Chemistry is probably the make-or-break element of any movie romance, but it wasn't ever an issue for Gordon-Levitt (Stop-Loss) and Deschanel (Yes Man). ''I adore Zooey,'' beams Gordon-Levitt. ''She's the most beautiful girl making art right now.'' Echoes Deschanel: ''He brings out the best in me. I just kinda wanna do, like, every other movie with him. We kept going, 'Let's become the next Tracy and Hepburn!''' She pauses. ''I mean, these are lofty goals.'' Even more lofty is the filmmakers' hope of reviving the romantic-comedy genre — employing split screens, animated title cards, a postcoital dance sequence, and a time-twisting story line that hops non-chronologically through a relationship between a greeting-card writer (Gordon-Levitt) and his girlfriend (Deschanel). ''It's what it's actually like to remember something like this,'' explains Gordon-Levitt. ''You remember the day you met, but then that reminds you of some other great date, and that reminds you of the first time you had sex. We're betting the audience has probably felt some of this before, and knows that it's no simple matter, love.''
