I think we're looking for a really nice guy, basically, to play the Maia (associated with Yavanna) who later on becomes Radagast the brown. I think he appeared in season one briefly or did a cameo, and he will only appear in the background or shorter scenes this season, but he is important and we have to make him noticeable. I nominate Dev Patel. He is 26 years old (of course, as all actors who play Maiar are). He is a well known actor and will be noticed, and he seems to be a really nice guy, so, there it is.
