There has been plenty of efforts to do this but for one reason or other, all have foundered or not been carried through.
On the subject of Highlander, what came first, Highlander or Casca? Highlander was written originally by a Canadian university student in around 1983 or 1984. Casca had been written and published in 1979. Who’s to say this student hadn’t read Casca and borrowed the general idea of an immortal?
Besides, Casca as a series would be ill-served by the ‘flashback’ method. It’s already been done many times over. What Casca’s strength is, is the immersive there-at-the-moment series, of a warrior at that period of time fighting at that time. To reduce it to the easy-to-do and cheaper option of setting it in present day and ‘flashback’ is a cop-out, as far as I, and many others, are concerned.
I think the first Casca book would make an excellent first movie with sequels to follow. The best thing is the sequels do not need to follow the same ordering as the books and could even be new materiel or be batched (e.g. all the Gus storylines in one movie, etc.).
Get the Rock to play Casca… he is who I think of when I read your great stories.
Yes the first book would be a great film, and introduction to the Casca series. But I fear Hollywood or whoever takes up the responsibility would go down the cheap and safe option of doing a similar butcher job that they did to Highlander.
I was talking about that today on the podcast interview. Hopefully the interview will be available for you all to hear before long. I have no idea how long the podcast will be, as I was chatting to the interviewer for about 1 hour 15 minutes.
