Since memo's last one doesn't make a stitch of sense to me nor is it a horse's name I'll override it (I'm sure he won't mind) with another one.

13 fictional horses in film

1. Ginger - Black Beauty
2. Spirit - Spirit: Stallion of the Cimarron
3. Hidalgo - Hidalgo
4. Shetan - The Black Stallion
5. Goliath - Ladyhawke
6. Tornado - The Legend of Zorro
7. Flicka - Flicka
8. Sylvester - Sylvester
9. Jolly Jumper - Lucky Luke (can we count it?)
10. Concorde - Monty Python and the Holy Grail (most fictional of all, played by a page banging two coconuts together)
11. Gunpowder from The Legend of Sleepy Hollow\
12. Rigel - Ben-Hur
