Although Hayato Ikeda was credited as director of "M.D. Geist", it was actually Ohata who did the overall direction. Because Ohata was 23 years old and inexperienced at the time, the producers brought in Ikeda for appearances. Ohata admitted that the numerous animation mistakes found on the first title were a result of a disorganized animation team. The "Director's Cut" edition, co-produced by Central Park Media, smoothed out most of the animation errors and featured additional footage - including a new introduction and epilogue.
