Filmation can’t tell the difference between Hawkman and Birdman! The poor intern that put together the menu artwork for the Superman/Aquaman Adventure Hour DVDs “accidentally” dropped in production art of Birdman rather than Hawkman. In terms of mistakes on DVD releases I don’t honesty think that this rates that highly when compared with Texas Chainsaw Massacre invading Dr Who Netflix DVDs or the Back to the Future widescreen framing issues. Apparently some fans have been up in arms about it, but personally I find it hilarious. Black Vulcan and Apache Chief had appeared in Harvey Birdman, Attorney at Law so why shouldn’t he appeared in a few Justice League shows.
