The movie was actually shot entirely in English. This "international version" has a running time of 105 minutes. When it was released in the United States by National General Pictures, it was cut by six minutes. Although Toho's international version runs 105 minutes, its Japanese theatrical cut is just under 90 minutes long. All the dialogue is dubbed into Japanese. The film was also reedited in the 70s as part of Toho's Champion Festival. The international and Japanese cuts are available on DVD in the US.
