Harry Potter actors James and Oliver Phelps, Jessie Cave, Warwick Davis, and Mark Williams headed to Harrod's of London on Thursday afternoon, where they participated in a DVD signing of Harry Potter and the Deathly Hallows: Part 2 as part of Warner Bros' promotion for the BD/DVD launch for the finale, out Friday, December 2, 2011 in the U.K. SnitchSeeker was on hand at the event, where we got the chance to interview the cast about their final scenes and best memories of working on the series; highlights of that, which were also reported on our official Twitter, and photos of the event, can be read and seen here.

• Jessie Cave: my final scene on Harry Potter was when Lavender died.
• Warwick Davis recalled watching Ralph Fiennes as Voldemort slip over on blood during filming.
• Mark Williams closed his eyes when he went on the Forbidden Journey ride in the Wizarding World of Harry Potter. Williams also noted the crew don't get enough kudos and talked about a book put together detailing their contribution. Williams said there was so much waiting around on set that he sometimes had two breakfasts, with a nap in between!
• The food menu in catering changed on Harry Potter films set as the kids aged; from chicken nuggets to more sophisticated meals.
• Williams also paid tribute to WB for the way they protected and invested in HP and always let them be creative in decisions.
• The reporters were also told about a prank somebody played on an assistant on set to do with football and an intern. Very funny story.
• We told them about the newly announced theme park in Hollywood and it appeared to be news to the cast!
• Warwick Davis: the good thing about prosthetics versus CGI is that you can see the authentic performance underneath. His last day on set was filming in Gringotts.
• They all agreed the unsung heroes were the people in charge of their trailers on set, where they would retreat to between scenes.
