Count Duckula (Spin Off)

Danger Mouse was aired from 28 September 1981 to 19 April 1992. It was the longest running animated series from Cosgrove Hall Films and one of the most popular. It starred David Jason in his first original TV series for Cosgrove Hall. He was the voice of the title role and also the narrator.

It took place in London's area of Baker Street which is similar to Sherlock Holmes. Danger Mouse (the world's greatest secret agent) and his assistant Penfold had their headquarters in a red Victorian Royal Mail Post box in the corner of the street where their boss Colonel K would contact them if there was any mission they had to do. Most of the time they dealt with dangerous threats, most of them coming from their evil arch-nemesis Baron Silas Greenback, a diabolical toad bent on world domination. There were two main vehicles that were used in the series: the Mark III (a high speed car with wings) and the Space Hopper (a high speed space rocket for missions in space). It also introduced Count Duckula but as a villain. He would later have his own spin off show where he would be a vegetarian vampire duck. The show became a smash hit bringing fans from all over the world and it is near the same level of popularity as its spin off.

In 2015, the show was relaunched with differant animation, voice cast and effects.



Eighty Nine episodes were produced in this series, including two pilots:
