Good heartwarming musical adventure filled with thrilling plot twists, this film is a wonderful blend of live-action and Disney animation. This is a sort of a children's version of Harvey and another attempt for repeat the Mary Poppins magic. There are a LOT of songs, even for a Disney musical.
Settings look wonderful. I wonder if Passamaquoddy exists for real. Nevertheless, Passamaquoddy is one heck of a name.
Jim Dale as the unscrupulous Dr Terminus, and Red Buttons as his dim side-kick, are genuinely funny villains. The blending together of animated Elliot and the living, breathing actors is very good - especially for 1977 - though in a shipwreck sequence near the end the special effects are utterly dreadful.
