That’s right.
Michael Ende’s book is massive in scope and a single film won’t do.
Whether film or series, here you go:
The Neverending Story I: Quest For Phantasia
The Neverending Story II: Journey To The Oracle
The Neverending Story III: Age Of Balthazar
The Neverending Story IV: The Silver City
The Neverending Story V: The Water Of Life
