As you may or may not be aware, Downton Abbey's Lesley Nichol (Mrs. Patmore) will be making an appearance on Once Upon A Time in the an upcoming episode. As fervid Downton fans, this got us thinking about which other “upstairs” and “downstairs” actors we would cast in OUAT if given the chance. We previously cast Mary, Matthew, Lord Grantham, Anna, and Gwen as classic fairy tale character, and lucky for us (and you), there are more than enough actors on that show. So, here's part two!

Jessica Brown Findlay (Sybil)
We're still recovering from Sybil's tragic and untimely death, which is why we want to see actress Jessica Brown Findlay in the Enchanted Forest as soon as possible – so we can pretend that Sybil somehow magicked her way to Fairytale Land rather than bit the bullet. And, if we can picture anyone on Downton singing to cute, furry animals in a magical glen, it's Lady Sybil. Unfortunately, there aren't a lot of good fairy tale princess roles left up for grabs, so bird-friends will have to braid someone else's hair while Jessica fills the shoes of a different classic character.

With her ability to play wide-eyed wonder so well, we think Jessica would make an amazing twenty-something version of Wendy from Peter Pan. She's sweet enough to look after the Lost Boys, but bad ass enough to fight the pirates. And who wouldn't want to see OUAT reinvent Peter Pan canon and have Wendy fall for bad boy Hook (Colin O'Donoghue)? Come on, that can't just be us.

Laura Carmichael (Edith)
Poor Daughter No. 2... Edith has had a bit more to do this season, what with being abandoned at the altar and considering an affair with her married newspaper editor, but the girl still gets seriously ignored by the Crawley clan. If she had an Enchanted Forest/Storybrooke counterpart, we think it'd be Tinkerbell, the independent (and, let's be honest, a bit whiny) fairy who's constantly getting passed over for Wendy by Peter Pan. Laura Carmichael is cute as a button, and we think she would fill Tinkerbell's tiny shoes perfectly. Who knows? Maybe with our planned Wendy/Hook romance, Tink might finally have a chance with best buddy Peter. Or, Tink could ditch Pete and the Lost Boys and do her own thing. She's got the fairy dust for it!

Jim Carter (Carson)
We think Jim Carter could play any role (seriously, cast him as Pocahontas and watch him pull it off), but we do love him as the loveable curmudgeon Carson on Downton Abbey. On the surface, he's such a grump, but deep down, you know he's all marshmallow. We can't help but want to see more of Jim as a strict, but kind hearted rule-follower, which is why we dream cast him as King Triton from The Little Mermaid. There's already been talk of Ariel making an appearance on OUAT (in part one of our Downton casting, we suggested Rose Leslie for the role), and we hope she'll bring with her some of the supporting Mermaid characters. Jim as Ariel's loving but disapprovingly traditional father would be perfect. We all know Carson is really the one who keeps Downton in order. After that, ruling over an entire ocean kingdom should be easy!

Thomas Howes (William)
The Disney version of our favorite fairy tales are filled with animal characters. OUAT has mostly stayed away from them, but recently Cinderella's mouse friend, Gus, made an appearance (albeit briefly). We'd like to see OUAT bring some of our other favorite animal characters to life and, while we're on the subject of The Little Mermaid, we think Thomas Howes would make an excellent Flounder. He played Downton's loyal, sweet William who sacrificed his life for Matthew in Season 2, so we think he could handle the role of Flounder, Ariel's trusted fish friend. With his baby face, we also kind of think Thomas looks like Flounder (well, as much as a grown man can look like an animated fish). Thomas may have been born to fill this role.
