It's not easy to adapt a book.  If it were, we'd have better movies.  Also, it's next to impossible to adapt a series like Harry Potter, which has so many fans invested in every scene that choosing what to use and what to omit is like walking through a minefield.  And that's the reason why Steve Kloves needs to be congratulated. As the screenwriter of all the movies except Order of the Phoenix, he's done the impossible, and made it look easy.A few days ago, I was in New York City for the big Harry Potter and the Deathly Hallows - Part 2 press junket and I was able to sit down with Kloves for an almost thirty minute interview.  If you're a fan of the Harry Potter franchise, I promise you this is a must-watch interview.  He talks about how he writes, does he read message boards, has JK Rowling told him any secrets that haven’t yet been revealed, what is he happiest with in the series, what mementos did he manage to keep, deleted scenes, is he nervous to write another franchise, and so much more.  In addition, he also talked about what it was like to work on the script for Marc Webb's Amazing Spider-Man.  Again, I can't recommend this interview enough.  Hit the jump to watch.For more of my exclusive video interviews for Harry Potter and the Deathly Hallows - Part 2, here's director David Yates, producer David Heyman, Rupert Grint, and I also stopped by Harry Potter:  The Exhibition at Discovery Times Square while I was in NYC.  And if you just want to watch what Kloves said about Spider-Man, we posted it earlier this week.As usual, I've time indexed the interview so you can watch the parts that interest you.Finally, if you haven't read the books, you might want to watch the interview after you've seen the movie.  Or avoid 10:30 - 12:00 as we talk about the ending.Steve Kloves Interview Time Index

• 3:50 Has Rowling told him any secrets that haven’t yet been revealed? He says she has.

He sees Part 1 and Part 2 as a whole. They work as two separate movies, but they can play like one big movie, so they wanted to make sure the ending worked rhythmically well. He says they didn’t want to overstay their welcome.

• 15:04 Talks about how they’re approaching the reinvention of Spider-Man. Are they going for a more cartoony tone of the first three films, or are they grounding it more in reality like Iron Man?

He also talks about his impression of Sam Raimi’s Spider-Man films.

• 24:07 His writing process. He wrote The Fabulous Baker Boys from midnight to 4am, but he had to be disciplined when writing Harry Potter. In 13 years he says he doesn’t think he was ever more than 72 hours away from Rowling’s text, it was all-consuming. Years ago his most enjoyable time to write was 5am to noon.
• 26:08 When he wrote Deathly Hallows, did he write the two parts separately? He says he wrote them as one long movie.
• 26:24 Did it take twice as long as the other scripts to write Deathly Hallows? He felt it was important for the movie to be emotional, he wanted each death to be significant. He says he worked at least twice as much on Deathly Hallows than the other films. It took him over a year. He said he wasn’t very happy with his first draft of the script, but he was really happy with his second draft, which is uncommon for his scripts.
