I'm still bothered that the casting sheets said "All ethnicities" for most of the Rangers but specified "Caucasian" for the Red Ranger. That's rather backward of them, considering how many nonwhite Red Rangers we've already had.
I see they're still shooting in New Zealand. I guess that means we'll be seeing some more familiar actors from Hercules, Xena, The Matrix, Legend of the Seeker
, or earlier NZ seasons of PR. (Although on LotS it generally went the other way, with former PR cast members showing up in guest roles there.)
