base the teleplay on May's original book, but could not find a copy. Other than Burl Ives, all characters were portrayed by Canadian actors recorded at RCA studios in Toronto under the supervision of Bernard Cowan. Rankin and Bass chose Canadian voice actors for two reasons. First, while the last radio dramas in the U.S. had ended production a few years previously, many were still being produced in Canada, giving the producers a large talent pool to choose from. Second, Rankin and Bass, financially stretched while making Tales of the Wizard of Oz a few years earlier, had been able to complete that series only due to the lower labor costs in Canada. Ives' parts were recorded later. He and his character were added to the cast just before the end of production, after NBC and General Electric, the show's sponsor, asked Rankin and Bass to add a name familiar to audiences to the cast. Character designer Antony Peters intentionally made the Sam the Snowman character resemble Ives. After the script, concept designs and storyboards for Rudolph were done by Arthur Rankin, Jr. and his staff of artists at Rankin/Bass in New York City. The company's trademark stop motion animation process, known as "Animagic", was filmed at MOM Productions in Tokyo with supervision by Tadahito Mochinaga and associate direction by Kizo Nagashima. Besides Rudolph, Mochinaga and the rest of the Japanese puppet animation staff are also known for their partnership with Rankin/Bass on their other Animagic productions almost throughout the 1960s, from The New Adventures of Pinocchio, to Willy McBean and his Magic Machine, to The Daydreamer and Mad Monster Party? In the original production Billie Mae Richards, who voiced Rudolph, was credited as "Billy Richards" since Rankin and Bass did not want to disclose that a woman had done the part. Antony Peters' name was also misspelled, as was the year of the copyright notice (which used Roman numerals), listing it as MCLXIV (year 1164) and not MCMLXIV, potentially weakening the copyright. The dolls for Rudolph and Santa cost $5,000 to make. Aftermath Since those involved with the production had no idea of the future value of the stop-motion puppet figures used in the production, many were not preserved. Rankin claimed in 2007 to be in possession of an original Rudolph figure. Nine other puppets—including Santa and young Rudolph—were given to a secretary, who gave them to family members,
