<P> The voice of Howard, Chip Zien, was not cast until after shooting completed . 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 . Gale often had to walk backwards before beginning rehearsals . In between takes, a hair dryer was stuffed in Howard's bill to keep Gale cool . Gale taped two of his fingers together to wear the three - fingered hands created for the Howard costume . A total of six actors gave physical performances as Howard . </P> <P> Gerber was impressed by the appearance of Howard, and commented, "It was very bizarre to meet it and...realize not just that I created it - that would have been bizarre enough...you know, it was sort of like meeting a child I didn't know I had ..." </P> <P> Makeup artists Tom Burman and Bari Dreiband - Burman and actor Jeffrey Jones discussed the appearance of the Dark Overlord character with Huyck and Katz, and developed the character's progressing looks . When Katz's daughter visited the set during the shoot, she was terrified by Jones' appearance in makeup . The diner sequence combines practical effects, including squibs and air cannons, with visual effects created by ILM . Sound designer Ben Burtt created the voice of the Dark Overlord by altering Jeffrey Jones' voice as his character transformed . Stop motion effects during the climax were designed by Phil Tippett, who began with a clay model before upgrading to more sophisticated pieces . </P> <P> After auditioning a number of actresses, singers, and models for the role of Beverly, Lea Thompson was cast in the role, because of her appearance in Back to the Future . Thompson purchased clothing from thrift stores because she wanted to appear at the audition as "a cross between Madonna and Cyndi Lauper ." During the shoot, Thompson complained that the filmmakers chose to shoot Howard's closeup before hers . Thompson also states that she regrets not wearing a wig, as her hairstyle took two hours a day to prepare . Jeffrey Jones was cast because of his performance in Amadeus . Although Tim Robbins had not appeared in many films, Huyck and Katz were confident that he was right for the part . </P>
