ABC has cast kiwi actress Rose McIver to play Tinker Bell in season three of its fairytale series “Once Upon a Time,” returning Sept. 29. The new season will find Snow White, Prince Charming and their grown daughter Emma Swan heading off to Neverland to rescue Bella’s son from a sinister Peter Pan.

Producer Adam Horowitz teased the Tinker Bell character at SDCC, suggesting that she, like Pan, will be a darker character than people have known her to be in the past.

Horowitz said:

It’s taking an icon and putting our spin on it. How we introduce her, and who she is, is hopefully going to be surprising because we’re going to find she has a surprising connection to someone.

McIver played Ranger Yellow Summer Landsdown on the kid show “Power Rangers: RPM” and made her feature film debut opposite Mark Wahlberg and Saoirse Ronan in Peter Jackson’s 2009 murder mystery The Lovely Bones.
