You knew it was a creature feature because Elvira was there.To get ready for his perf as creepy kid Edgar “E” Gore, Atticus Shaffer immersed himself in monochrome classics. “Because I had a character voice with a Peter Lorre accent, it was new for me. So to study up for the part, I researched ‘Arsenic and Old Lace’ and the ‘Maltese Falcon,’” he noted. As the toon’s young Victor Frankenstein, Charlie Tahan brought his beloved dog Sparky back to life. If he could do that in real life, he said he’d bring back “my rabbit, Cookie.” Burton celebrated at the Annex afterparty along with Disney’s Bob Iger, Alan Horn and Sean Bailey, pic’s Winona Ryder, Martin Landau, Martin Short, Catherine O’Hara, exec producer Don Hahn, producer Allison Abbate and scribe John August.
