Your death sits in that cage, and she hears you.

The Last Unicorn (1982)

Chosen by Victoria Charvill who had this to say about it: 'We only discovered this after looking for lists of the best kids films and I'm so glad we did. It has an A list cast and the core members of the animation team went on to form Studio Ghibli. It does have some cheesy music, but hey, it was the '80s. It is a kids film but it has enough adult themes that I can watch it over and over with my kids. A classic to rival any Disney film'

One of those childhood favourites that I had never even heard of until recently (a comic adaptation came out that I sold in store) but when mentioned people seem to love.
It's pretty decent until it stalls itself at an empty castle for what feels like ages, but the road trip, quest narrative until then was fun and a little dark, let down by Mia Farrow's weak voice talent (her duet with Jeff Bridges is terrible) and some dull, far too specific songs (there's little room for poetic metaphor, if they're singing about an eagle soaring, there is an eagle on screen) sung by the band America.
Tammy Grimes brings some life to the character of Molly who has an endearing look and holds the group together (more should have been made of this, by ditching the songs and playing up the relationships more perhaps?).
