While Sheriff Graham is long gone on Once Upon a Time, that doesn’t mean actor Jamie Dornan is gone from the Storybrooke family. As soon as news broke that he would be playing Fifty Shades of Grey’s titular kinky billionaire Christian Grey, the internet exploded, and the cast had plenty of feelings about the way in which, ahem, he'll use handcuffs now.

When Wetpaint Entertainment caught up with Colin O'Donoghue (Captain Hook) to chat about his big kiss with Emma and the Hook-centric episode "Good Form," he shared a sweet reaction to Jamie's casting, even though they never worked together. "I think it’s absolutely fantastic for Jamie," he said enthusiastically. "I met Jamie, but I didn’t work with him. But yeah, it’s an incredible opportunity for him, so I wish him the very best of luck with it!"

In the same vein, some of the actors took to Twitter to share their congratulations and general excitement for his next big role. Check them out below!

Josh Dallas (Prince Charming): “@JamieDornan1 is my Mr. Grey. #50ShadesOfDornan,” he tweeted.

Michael Raymond-James (Neal): “Let em know Jamie. #Boom,” he wrote, retweeting Josh Dallas.

Jamie Chung (Mulan): “Congrats to @JamieDornan1!!!!!! #50ShadesOfGrey,” she wrote, but also tweeted a link to her fashion blog, writing, “50 Shades of Grey? Nah, it's all about "50 Shades of Teal.”

What do you think of Jamie's casting? Sound off below.

Once Upon a Time airs on Sundays at 8 p.m. ET on ABC.
