From Mark Salisbury‘s “Burton on Burton“: “Warner Bros. management disliked the title Beetlejuice and wanted to call the film House Ghosts. As a joke, Burton suggested Scared Sheetless and was horrified when the studio actually considered using it.”
Just $1 million of Beetlejuice‘s $15 million budget was spent on visual effects, which included stop motion, replacement animation, prosthetic makeup, puppetry and blue screen. It was always Burton’s intention to make the style similar to the B-grade movies he grew up with. Burton: ‘I wanted to make them look cheap and purposely fake-looking.”
Wiki: “Test screenings geenrated positive responses, and prompted Burton to film an epilogue in which Beetlejuice angers a dead witch doctor.”
