Kreacher and Dobby first appear when Harry summons Kreacher to help him locate one of the Horcruxes, in the form of a locket held by Mundungus Fletcher. The two elves capture Fletcher and, clutching him, apparate back to Harry. Dobby's second appearance in the film occurs when he comes to rescue the three heroes from the clutches of the Death Eaters at Malfoy Manor. As they make their escape via a disapparation, Bellatrix hurls a knife which hits Dobby. Apparating on a desolate beach, Harry finds that his faithful friend is mortally wounded. In a profoundly moving scene, and the emotional climax of the film, Dobby dies, cradled in Harry's arms.

An important pre-production decision – one that played to Framestore's strengths – was that the two elves would be keyframe animated rather than 'acted' through motion capture. This followed a proof-of-concept demo prepared for Yates and Burke by a small team led by VFX Supervisor Christian Manz, Lead Animator Pablo Grillo and CG Supervisor Andy Kind in February 2009. 'Mo-cap is often Directors' and Supervisors' first choice when looking for photo-real humanoid performances', Animator Pablo points out. 'But with mo-cap you get "everything", which can result in that slightly queasy, uncanny valley sort of look. Our animators were able to carefully craft emotive and believable human performances from careful observation of a variety of sources'. Burke persuaded Yates on the importance of having the voice actors on set and performing on film, and with these performances as reference, together with the animators' research (including photographic studies of Framestore's oldest employee), and, vitally, their own imaginations, the Framestore team was able to engineer a staging that worked convincingly within the context of the edit and the quirky physicality of the House Elves.

The rescue sequence at Malfoy Manor was notable from Framestore's point of view for its particularly demanding disapparation. To highlight the drama of Bellatrix’s hurtling knife flying towards and into the group as they are transporting away, Yates asked that the shots look as if they'd been filmed on a Phantom camera, i.e. in merciless slow motion. Shot at Freshwater West in Wales, the gritty location shoot featured a Dobby-sized body double and a dummy. Compositing Supervisor Christian Kaestner led the 8-strong compositing team. 'The dummy and the body double became lighting reference for Framestore while integrating the animated character into Radcliffe's arms', he says. 'Tim Burke shot a lot of reference and clean plates, but the takes that David Yates chose were the ones of Harry interacting with the stunt double. That required a lot of paintwork, so we went to Leavesden and shot texture reference of Harry's wardrobe and Radcliffe's hands, and we used those textures to rebuild parts of Harry that the double had obscured. We then restored areas of Harry's jacket, his shirt and hands by re-projecting and animating textures'. At the moment of his passing Framestore made Dobby's eyes appear watery, and desaturated his skin textures to make him wan and pale.

At an earlier point in the film, Hermione is directed to read aloud a story from The Tales of Beedle the Bard, her book of fairytales. The story is a wizard folktale about three enchanted artifacts – ‘The Deathly Hallows’ – that grant their owners dominion over Death. To take the audience into this tale within a tale, the production hit upon the idea of an animated interlude depicting the events as Hermione narrates them. The result is a stunning, almost 3 minute sequence, directed by Ben Hibon and created by a 37-strong crew drawn from Framestore's Commercials team, led by Sequence Supervisor Dale Newton.
