As Thor 2 gears up for production, the search is now to replace Joshua Dallas, who played Fandral, one of the Warriors Three, in the 2011 original. EW reports that, due to the actor's commitments to ABC's "Once Upon a Time", the role will be recast.

The film is set to mark the third big screen appearance of Chris Hemsworth's Thor and Tom Hiddleston's Loki. Natalie Portman, Jaimie Alexander and Idris Elba have been confirmed to be returning for the Alan Taylor-directed sequel as well, though even more of the first film's cast likely to be back as well.

Oddly enough, Dallas was not originally cast as Fandral in the first film and was a last-minute replacement for Stuart Townsend, who departed over creative differences in January of 2010.

Featuring a screenplay by Robert Rodat and Don Payne, Thor 2 is scheduled to be released on November 15, 2013.

UPDATE: The Hollywood Reporter has word that "Chuck" star Zachary Levi is in early talks to take on the role.
