If any other non-disney shows/movies become a part of Once Upon A Time, which shows/movies would you like so see a part of?

Merlin! I'd LOVE ONCE to delve deeper with the 'Camelot storyline' as they've touched upon it in several episodes. And besides, 'The Adventures of Merlin' is an AWESOME show! It's my fav show along with OUAT! It has many awesome characters & storylines that stay true to the original legend but with various twists throughout the show, ONCE style! Some of the cool characters (Merlin, Morgana, Gwain etc.) would fit right into the OUAT universe! *^_^*

I would love to see tarzen incorperated some how into the movie when I was little I loved that movie so much me and my mom we bought the soundtrack and to this day we still have it.

There's a movie called Stardust which I think would be cool to see the characters be incorporated into the show. I think it's actually based on a book but I've watched the movie and I really love the witches in it so I think it'd be cool to see Regina and/or Rumple meet them.
