Despite co-star Jamie Dornan moving on to star in Fifty Shades of Grey, the cast of ABC's Once Upon a Time is still hoping to get him back.

Dornan, who is set to play the lead role of Christian Grey in Fifty Shades of Grey, played Sheriff Graham Humbert in the first two seasons of Once Upon a Time, and the rest of the cast wants him to return, particularly Jennifer Morrison (who plays Emma).

"We're still good friends and obviously Jamie has quite the schedule," Morrison explained to E! News. "But we're hoping that someday there will be a moment where he's available to come back and reprise some flashbacks of Sheriff Graham."

Josh Dallas, who plays Prince Charming on the series, could not help but admit, "Mr. Dornan's sexy!" adding, "I can't wait to see the movie. I'll be the first one there."

Lana Parrilla, who plays Regina, found the trailer for Fifty Shades of Grey "pretty sexy," saying she "saw a different side of Jamie."

Dornan's Sherriff Graham died in Emma's arms in Season 1, having his heart crushed by Regina. Despite this, anything is possible in the magical world of Once Upon a Time so a return for Dornan is always possible. He could conceivably return for a flashback in the future, as Morrison suggests.

For now, however, he will be busy attracting attention as Christian Grey when Fifty Shades of Grey is released in theaters on Valentine's Day 2015.

Once Upon a Time Season 4 is set to premiere Sunday, Sept. 28 at 8 p.m. on ABC.
