'Once Upon A Time' Season 5 Spoilers: Hook Tries To Summon Emma In Sneak Peek Clip; Plus 15 Juicy Details

At Disney's D23 expo this past weekend fans of "Once Upon a Time" were treated to an all-new sneak peek clip. In the video we get to watch the first minute of the new season after Emma Swan (Jennifer Morrison) is enveloped by the dark ones essence.

In the minute-long clip, which comes from the season five premiere "The Dark Swan," we see what happens immediately after Emma absorbs all the dark ones essence. After being surrounded by the dark cloud Emma is transported away from Storybrooke. Hook (Colin O'Donoghue) then tries to summon Dark Emma using the dagger with no success. Regina (Lana Parrilla) then informs him that she wasn't returned to the town becuase she's not in their world.

We cannot wait to find out what happens after the events in the new sneak peek clip but unfortunately we will have to wait until the premiere, which will air on ABC Sunday, Sept. 27, at 8 p.m. ET. Untilt then check out these other 15 exciting details about "OUAT" season five after the jump.

1. New and returning stars include Sinqua Walls as Lancelot, while Gabe Kouth and Lee Arenberg confirmed via social media they would be returning as Sneezy/Tom Clark and Grumpy/Dreamy/Leroy. On July 10, Beverley Elliot and Keegan Connor Tracy confirmed via Twitter they would be returning as Widow Lucas/Granny and Blue Fairy/Mother Surperior, while it was also revealed Elliot Knight, Joana Metrass and Andrew Jenkins have been cast as Merlin, Guinevere and Percival.

2. Zap2it spoke to the shows creators Edward Kitsis and Adam Horowitz who revealed Emma may be dark for most of the coming season. When asked to describe season five in one word, Kitsis replied "Swan." Though extremely vague, the one word suggest that bringing Emma back from the dark will be the central theme of "OUAT."

3. The writers for "Once Upon a Time" are currently taking a well deserved break, but according to Horowitz the theme for season five has already been talked about.

"We start with a theme we want to explore and go from there," he says. "We've done our mini-camp. We actually have the next month so we like to sit for the next month and ask 'Does it still hold true?'"

4. Don't expect to meet Merlin right away as there is a quest to find powerful sorcerer. The season will detail the characters' quest for Merlin in order to free Emma from the powers of an ancient darkness and to defeat it once and for all before it destroys everything.

5. Rumplestiltskin (Robert Carlyle) is still alive but for how long is up for debate. In the season four finale "Operation Mongoose, Part 2" the darkness was pulled from Rumple and he was left in a critical state and put in a kind of stasis with his condition unknown. On the bright side Carlyle is still on the casting list for season five so we know Rumple will be in the series in some sort of capacity.

6. Looks like the Wicked Witch and Robin Hood will be sticking around for some time. Rebecca Mader and Sean Maguire have been promoted to series regulars for season five of "Once Upon a Time" Entertainment Weekly reports.

7. We have found our King Arthur for season five of "OUAT." It was revealed early last month that Liam Garrigan ("24: Live Another Day") will play Arthur reports EW. "Once Upon a Time" will put their own unique spin on Arthur's story and his relationship with the still unannounced Guinevere and Lancelot.

8. It has been confirmed that Mader's character, Zelena the Wicked Witch, will give birth in season five. This means there will be a new baby witch in town and again Regina will be a stepmother.

9. Michael Socha has been demoted to recurring cast member. If you recall the Knave was brought to Storybrooke when "Once Upon a Time In Wonderland" ended as a series regular but it looks like his role will be less than when "OUAT" returns this fall.

10. Two "OUAT" promo trailers were shown at San Diego Comic-Con. In the videos we get our first look at Dark Emma in action and are introduced to Merida from Disney's "Brave." Check out the trailers below:

11. Amy Manson, who plays Merida, shared a pic of herself on the set of "OUAT." The actress was cast as the "Brave" princess but turns out Manson has some catching up to do. She posted to Twitter showing off a selfie of herself with season two of "Once Upon a Time" with a caption that reads: "Oooooo...Watching series 2 on lunch break from filming ;) #OUAT #merida." Check out the tweet below:

12. Colin O'Donoghue who plays the lovable Captain Hook on "Once Upon a Time" spoke with IGN and revealed some interesting details about what his character will be doing in season five and also shed some light on Hook and Dark Emma's relationship.

It's a short clip but O'Donoghue starts off by talking about how Hook desperately wanted to keep Emma from falling into the darkness in season four and now that she is there he will do anything to get the woman he loves back. He also compared the way Belle (Emilie de Ravin) sees Rumple is the same way Hook sees Emma so he'll never give up on her. Check out all the details in the interview below:

13. In a recent interview with BuddyTV Lana Parrilla, who plays the Evil Queen Regina, revealed "I think Regina's going to become the savior this year and the hero." It wouldn't be a surprise to see Regina step into the role of savior as she has slowly but surely been changing her ways. She also mentions that Regina will be worried for Emma as she knows what it is like to walk down the path of darkness.

Furthermore, Parrilla talks about Henry (Jared Gilmore) being the author and reveals his storyline may be delayed as the hero team needs a new magical quill. Parrilla talks more about Emma, Henry and even Zelena in the interview below.

14. We have learned the first three episode titles for "OUAT" season five. The premiere episode is titled "The Dark Swan" and will air Sept. 27. It is directed by Ron Underwoodand written by creators Edward Kitsis and Adam Horowitz. The second episode is titled "The Prince" and is written by Andrew Chambliss and Dana Horgan, while the third will be called "Seige Perilous." It will be directed by Ralph Hemecker and written by Jane Espenson.

15. EW revealed an exclusive first look photo from the coming fifth season of "OUAT," in which we see our former savior getting guidance from the former dark one, Rumplestiltskin. Furthermore, executive producers Adam Horowitz and Edward Kitsis coyly teased the photo saying, "If you’re going to be the Dark One, gotta learn from the best."
