Made by Gerry Anderson's then company 'Pentagon films' as a calling card to show off their puppetry and film making skills, possibly with an eye to being commissioned as a full series if financing could be found. Surprisingly it was made in Eastmancolor so it is possible it may have also been made with the childrens cinema Saturday morning pictures market in mind. Gerry Anderson and associate Arthur Provis set up their new company AP Films soon after and received their first commission soon after.
