So far only one movie for the series Thundercats. The movie was released year 1986 on VHS. This movie of greatness was to be named ThunderCats - HO The Movie, which was only sold, and broadcast in the UK and North America at that time. Soon enough the moive was cut into smaller versions, at episode length(around 30 minutes) and was edited to become 5 episodes. Each one of these episodes were sold seperatly, and eventually followed towards the second season.
