According to
this newsletter and also
previous newsletters, work is still proceeding on an anime movie adaptation of the first novel in
Piers Anthony's Apprentice Adept series,
Split Infinity, which has werewolves as well as shapeshifting unicorns. Also, towards the end of the series, shapeshifting aliens show up, but they might not go on to adapt anything beyond the first novel, so we'll have to wait and see.
The novel series is about Phaze and Proton, two linked worlds, with one being based on science and the other on magic. On Phaze, the humans are dominant, with unicorns, werewolves and vampires being the most common non-human species. The unicorns are the only ones who get to choose their forms. Each unicorn can turn into two (or rarely three) other forms, and normally one of those chosen forms is human. Refreshingly, instead of there being a vampire/werewolf war or rivalry, as is found in so much fiction, the unicorns and werewolves are sworn enemies instead.
In related news, Warner Pictures has dropped their plans to make a movie based on
the first novel of another Piers Anthony series, the
Xanth series, however Disney is still apparently going ahead with plans to turn the
Incarnations of Immortality novels into a TV series. The
Xanth series did not have extensive shapeshifting until a number of books in, when shapeshifter
Prince Dolph became a main character for awhile. The
Incarnations of Immortality series has a horse who can shapeshift into any vehicle, and that's about as much shapeshifting as you get. So, of the three Piers Anthony series that had been optioned for TV or movies,
Split Infinity is the one with the largest amount of content for shapeshifter and werewolf fans.
