Quick note re: the casting of Alex Kingston on Arrow—they’ve also cast Colin Salmon, who played Dr. Moon in Silence in the Library/Forest of the Dead, as Oliver’s stepfather, Walter. Fans for sure!
And John Barrowman. If Arrow gets to have many seasons,...Doctor Who could end up on it!
I also just remembered, on...Arrow being a fun little Doctor Who reunion, Ben Browder...
Not to mention Captain Jack as Merlyn.
