On David Yates' view on making the films: Dan said that Yates has the ability to see the entire film just from one still.
On Alan Rickman, David said he loved his eyebrows, while Dan loves his dry sense of humour.
Dan loved Lupin as a Defence Against the Dark Arts teacher and even noted that David Thewlis gave him tutoring lessons on Twelfth Night.
On Bellatrix: Dan thinks Bella is childlike and also evil; David said that you look in her eyes and she feels a little bit out of control. Dan stated that he's become a bit like Helena Bonham Carter's personal assistant on the set of Deathly Hallows, in that he's constantly picking up after her.
Dan and David were gushing over the quality of the Half-Blood Prince Blu-ray (it was the first time Dan used it). Dan noted that Emma's image on Blu-ray is her only competition in terms of beauty.
Tom Felton began filming Deathly Hallows at the end of the summer; he and Dan became good friends through Tom's girlfriend, Jade, who is one of Dan's best friends.
On their favourite CGI sequences in the Harry Potter series: David said it was the sixth movie's Inferi and cave set. Dan said one of his favourite scenes to film was the dragon chase in Goblet of Fire.
Dan was asked if he would consider joining Twitter, but he said no. However, he does like the idea of it and interacting with fans. He said that being able to convey a thought in 140 characters or less would be a challenge for him.
Choosing between Slughorn and Snape as a better Potions Master, they said that since Slughorn taught Snape, he would be better; Dan noted Harry's bias against Snape, and that he would prefer Slughorn more.
Dan noted that while Slughorn and Ron are rather outgoing characters on-screen, Jim Broadbent and Rupert Grint, respectively, are shy off-screen.
They both spoke about Hero Fiennes, who played young Tom Riddle in Half-Blood Prince, and as he is Ralph Fiennes nephew, he was "a young Voldemort in training."
For the birds used in the Vanishing Cabinet Draco uses in the Room of Requirement in Half-Blood Prince, Dan said it took him a few readings to figure out its significance.
On Deathly Hallows filming, Barron said that filming will end around late-spring early-summer, then there's the dubbing stage, and post-production. They will be doing work on it for another year, at least. There are plans for Leavesden after the movies are done.
Butterbeer tastes like J-20 with froth on it, according to Dan. They both mention that real Butterbeer will be sold at the Harry Potter theme park next year (Barron said it tasted very nice).
Dan said that he does have a say in Harry's costuming, in that his clothes should "look good, but look forgettable," given his origins. As the movies go on, the kids are seen less and less in their Hogwarts robes.
Dan said that his stage work in Equus has made him more confident as an actor, both on stage and screen, especially given how exposed he was in front of thousands of people live.
On wearing Muggle clothes in the series, as they got older, it paralleled to the fact that Muggle students around 16-17 in schools wear regular clothes and not uniforms. Plus, it shows them as more adult-like, according to Dan.
For the Great Hall scene, Dan noted he loved the colours in the scenes (the Gryffindor robes), and Luna blinking lion's hat. They give love to Evanna because of her artistic merit and what she brings to the character.
On Ron and Lavender's kiss, Dan said he lost all professionalism that day and teased and joked with Rupert all day. He said that Matthew Lewis teased him on the Order of the Phoenix set about Harry and Cho's kiss, so it was time for revenge.
Dan lists Rupert's cars: bright-orange Range Rover; ice cream van that was recently repaired and does actually make ice cream; he used to have a mini-cooper with Knight Rider designs; a Chevy pick-up truck that never works (which he brings onto the set to show off); and a hovercraft. He said that Rupert wouldn't be the kind of person to show off what he bought, and would just mention it in passing. David also got night-goggles for Rupert so he can ride on his hovercraft in the dark.
Dan and David's favourite Weasley is Ron, though they are fond of the entire lot.
On British actors they couldn't get into the films and wanted to, they list: Judi Dench, Helen Mirren, Daniel Craig, Juliet Stevenson, Ricky Gervais.
They said that the Burrow set is "cramped and crooked."
Dan said that the easiest scenes to film are action sequences, because he can throw himself into it. During the Burrow scene when Harry sees the fire and runs after Bellatrix, Dan noted that it was "terrible parenting," and wondered why the adults didn't stop Harry or Ginny from running off.
Dan and David confirmed that the five actors - Dan Radcliffe, Rupert Grint, Bonnie Wright, Emma Watson, and Tom Felton - will play their adult selves in the epilogue.
The pair said that their favourite villain in the series is Voldemort, of course, the embodiment of evil.
Dan mentioned that when he found out Richard Harris, the original actor who played Albus Dumbeldore, died, he just cried and cried. He also remembered having rather enjoyed filming the scenes with Fawkes in Dumbledore's office from Chamber of Secrets, because it kept speaking back to him.
Dan's favourite set is the Ministry of Magic atrium; David's is the Gryffindor common room for its warmth and detail.
Between Colin Creevey and Lavender Brown on who would be more annoying, Dan and David said that Colin's sweet, but Lavender's a bit irritating.
Dan on the Sectumsempra scene was like he and Tom "playing cowboys and Indians."
Dan said that he's broken about seven wands on set; Devon Murray about eight; but David Thewlis holds the record at about 12.
Dan said he'd be put into Hufflepuff ("nice, but clueless"), but really they'd like to be in Gryffindor, since they know it the best.
David's favourite plant are the mandrakes; Dan's is the Devil's Snare, which he found cool, but not something to get caught in.
Dan said that he was the one who told Gary Oldman that Sirius died on the set of Prisoner of Azkaban in 2003. When Harry mourned Dumbledore's body at the end of Half-Blood Prince, Dan said that Michael kept pulling faces to distract him.
Dan mentioned that Michael Gambon had not yet begun filming scenes for Deathly Hallows (and was admonished by David for letting that information slip).
Dumbledore's funeral will NOT be in Deathly Hallows, even if it wasn't in Half-Blood Prince. It was discussed between the Davids and Steve Kloves, but they felt it was just too many endings for the film. They tried hard to keep it in, but felt the balance was wrong, according to Barron.

Dumbledore's office
*Dumbledore's office, a quiet retreat and study for the sage Headmaster, was located in one of the highest towers of Hogwarts. Dumbledore's fascination with the universe and the skies became the room's defining feature.
*One of the most expensive props in the film was the working telescope in Dumbledore's office which was rarely seen on screen.
*On the shelves in Dumbledore's office are hundreds of books, many of which are actually old phonebooks covered in leather and dust.
Gryffindor common room
*The Gryffindor common room and the boys' dormitory were actually built as two connected sets. The staircase spirals up to a hallway that in one direction led to the boys' dormitory set. In the other direction a doorway simply drops off into nowhere.
