Ultraman, Ultraseven: Great Violent Monster Fight

A movie specially created for the Circularama Theater, a 360-degree screen that was located at the Korakuen Amusement Park in Tokyo. Featuring Booska and Chamegon, the 15-minutes film was comprised of stock footage from episodes of Ultraman and Ultraseven, and newly filmed material. No copy is known to survive. A reconstructed video (with 10 little screens instead of one) was included as a bonus on some old Ultraman Laserdisc.
