Charlie Strapp and Froggy Ball Flying High (1991 film)
In the early 1980s, Charlie Strapp and Froggy Ball were frequently featured in various Swedish radio series during the summers. When listening to one of these Jan Gissberg got the idea of making an animated film about them and contacted Thomas Funck. Together they discussed the desirable appearances of the characters and settings. The project was to be produced by Gissberg's own recently started animation studio, Cinemation Industries, where also his brother Peter Gissberg worked as a background artist. Around Christmas 1987 a short film was released, but already a year prior to that, they had begun working on a script for a feature-length film. In 1987 they started the process of making it, using a budget of 13 million SEK.
