After the international success of the preschool series The Adventures of Colargol, Procidis created between 1978 and 2009 the seven-series saga Once Upon a Time…: Man, Space, Life, the Americas, the Discoverers, the Explorers and Planet Earth, today all restored and encompassed with the licensed products under the umbrella brand Hello Maestro!
Dealing with historical and scientific topics carefully researched and documented, the 7 first series are evergreens and have been a reference in educational programs through screens for the past 40 years. Translated into 80 languages, they are well known in more than 100 countries.
They are broadcasted on TV channels (France 4, TV5 Monde, Cartoonito, Gulli Brasil…) as well as on platforms (Okoo, Netflix, Amazon Prime Video, Tim Vision…).
In 2024, Maestro, our protean hero, returns in Once upon a time… Objects (78 x 7’), a new series dedicated to everyday objects in a resolutely cartoonish and contemporary spirit! Co-produced with French Samka Productions (Wolf, The Sisters…), France Télévisions, TV5 Monde, RTS and HOT in Israel are already on board.
The Adventures of Colargol, the preschool musical tale with universal and family values, is coming back on the big screen in a wonderful HD remastered version.
