Oh, one more thing. I rewatched the pilot and the wolf that stopped Emma's car didn't have a red eye. Hmmmm.
This Wikipedia site has some good info but I'm never sure about the accuracy of Wikipedia:
http://en.wikipedia.org/wiki/List_of_Once_Upon_a_Time_characters
Grumpy (Lee Arenberg) is one of the seven dwarfs who gave Snow White shelter while she was hiding from the Evil Queen. He was also a guard in a watchtower in Snow White and Prince Charming's castle. His Storybrooke counterpart is Leroy, the resident troublemaker, and the janitor at the hospital.
Actress Amy Acker has been announced in recent casting news to play a love interest for the character of Grumpy in an upcoming episode.
The Magic Mirror (Giancarlo Esposito) is a spirit imprisoned by the Evil Queen. (there is more in the link but it is a bit spoilerish so didn't want to post it just in case).
The Blue Fairy (Keegan Connor Tracy) is a character from Pinocchio. She creates the Red Quill, which helps Cinderella and Prince Thomas imprison Rumpelstiltskin.
(Did we know that?) However, when it comes to magic, she cannot undo the work of Rumpelstiltskin.
Sneezy (Gabe Khouth) is one of the Seven Dwarfs. He suffers from hay fever.
His Storybrooke counterpart is Mr. Clark.
(who is Mr Clark?)
The Fairy Godmother (Catherine Lough Hagquist) is a character from Cinderella. Rumpelstiltskin kills her to obtain her magic wand just as she is about to turn Cinderella into a princess before the ball.
(Didn't Rumple ask for a magic wand when he bargained with King George?)
King George (Alan Dale) is the adoptive father of the first Prince James. He gives Rumpelstiltskin the location of the Fairy Godmother in exchange for Rumpelstiltskin bringing him James' twin brother.
(Did we see this or could it have been edited out?)
There are more spoilers about Hansel & Gretel and Beauty & the Beast but those episodes haven't aired so, if you want to read the spoilers, follow the link.
