These images are provided for review purposes only and remain the copyright of whoever holds the copyright today (if they let me know I'll give a proper acknowledgement). These images are from a TNT satellite broadcast several years ago, of a shorter version with most of the violence omitted. The original Japanese film, which I was lucky to see in 1959, had extended violent scenes.
A short Official trailer from Youtube, from the Warner Archive
I have been looking for an English version of this movie for years, but try looking on video channels for the German version which is called: Der Zauberer und die Banditen. Try asking Fox or TOEI for a DVD release.
2021- It looks as though WARNER ARCHIVE - NOW HBO Max- may be a good source to try as they have released an official trailer. HBO Max is streaming only, USA only... subscription. Sky own HBO rights in the UK but HBO Max is excluded. So you may need to wait until after 2025 to watch Magic Boy in the UK....
Working as an inbetweener on this early film was Rin Taro (sometimes Rintaro), real name Shigeyuki Hayashi, also used the name Kuruma Hino. He later worked on many classic anime series as producer or director, including my beloved Moomin , Art Director on Kimba the White Lion (1966)(no similarity to The Lion King at all...); Captain Harlock, Dr Slump and Arale, Phoenix, Time Stranger, and all the way up to the modern anime (2001) Metropolis, which I also saw on the big screen. My anime collection includes so much of this mans work - and he worked on the anime I first saw...
Another inbetweener on Magic Boy was Gisaburo Sugii, and again I have some of his later work, notably the magnificent Night of the Galactic Railroad, which he directed.
