 Because Ed Gale's voice was difficult to hear when he wore his suit, Huyck ordered Gale to perform his scenes without speaking any of the required dialogue, which was later synchronized during the editing process.Lead puppeteer Tim Rose was given a microphone attached to a small speaker, which would allow Rose to speak the dialogue to help the actors respond to Howard's dialogue.While wearing his suit, Gale could only see through Howard's mouth, and had to sense his location without proper eyesight.
