A reader, Ulysses G. asks:
The idea informing Lucan was something like Francois Truffaut's The Wild Child (1970) meets The Man from Atlantis (1976) meets The Fugitive.
Young Lucan had to learn about society and tame his savage ways at the same time he conquered his amnesia about his early, human identity. In the series, he was pursued by a bounty hunter (Don Gordon) while he attempted to "find himself" and otherwise help out innocent people.
Like you, I'd love to see a complete series DVD release, but as you also (correctly) note, this series is extremely obscure, and, alas, forgotten. Thank you for jogging my memory, and reminding us all of another 1970s treasure that should be excavated and made available.
