Additional Information about the The Marvel Action Hour (Series)

At the beginning of each show, Stan Lee was featured speaking before each show about characters in the following episode and what had inspired him to create them. The first show would be a full thirty-minute episode of Iron Man; the second half an episode of Fantastic Four (many episodes of which were direct recreations of episodes from the original DePatie-Freleng Enterprises series).

For United Kingdom showings, additional editing was needed. As the BBC not feature commercial breaks, the two shows that made up The Marvel Action Hour run time was only about forty minutes, and so episodes of the 1980's Incredible Hulk series were added between the two original shows to bring the show up to the full hour in length.

For the second season, both the Fantastic Four and Iron Man were radically retooled, with new opening sequences, improved animation, and more mature writing. Dropped were the introductions by Stan Lee.

In some markets, the second season was known as Marvel Action Universe (with the addition of Biker Mice From Mars), which was the name of a previous syndicated programming block in the late 1980s.
