Star of the cult TV series, Chuck, Zachary Levi is in talks to replace Josh Dallas in the Thor sequel says Heat Vision.
Levi was initially up for the role Dallas played, as one of the three warriors who backup Thor, but had to pull put when Chuck was unexpectedly picked-up for another season. Ironically, Dallas had to bow out because he just had his own show, Once Upon a Time picked-up and scheduling was an issue.
Alan Taylor, who has helmed numerous episodes of Game of Thrones, has replaced Kenneth Branagh in the director's chair.
