In a previous post, I mentioned that there are several Marvel Comics animated series that have been released in the UK but not in the US. One of these series was the 1978 Fantastic Four series, which is the second Fantastic Four that was created. (The first has not been released anywhere.)
The 1978 series is notable for replacing the Human Torch with a robot named H.E.R.B.I.E. There were rumors that the Human Torch was excluded because the writers were worried about children imitating him by setting themselves on fire. These rumors are false (his rights were tied up thanks to a movie that never actually got made).
The series is not available in the United States. However, the complete series (all 13 episodes) is available in Region 2. So, if you like in the UK or have a region-free DVD player, you can watch it. Otherwise you’re out of luck.
