ABC's Once Upon a Time posits a world in which our reality intersects with that of one populated by characters from fairy tales. Considering the huge pool of source material, it should come as no surprise that the new drama will utilize plenty of guest actors. And when you consider the show was created by two of the writers of Lost, Edward Kitsis and Adam Horowitz, and produced by Damon Lindelof, the odds some of those guest stars will be former residents of that mysterious island increases greatly.

So far, Alan Dale, who played Charles Widmore, has signed on to appear as Prince Charming's father, but he's not alone! TV Guide reports that Emilie de Ravin, better known as Claire to Lost fans, will play Belle from Beauty and the Beast.

TV Guide also says that plans for the Beast have yet to be revealed, and that rumor has it Belle will have dealings with series regular Rumplestiltskin, played by Robert Carlyle. Gaston, the man who hunted the Beast, is also rumored to appear.

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