Much like The Myrka costume in Warriors of the Deep: Part Two (1984), The Magma Beast costume was barely finished before it was needed in the studio, meaning that the performer inside the suit was given virtually no time to become accustomed to it. John Nathan-Turner was very disappointed by the finished product, although he had no choice but to allow taping to proceed.
